OUR HOME LIBRARY (PART II)


ENGLISH BOOKS FOR READ-BY-YOURSELF GROUP

The category Read by yourself is an elaborated version of many of the earlier fairy tales; classics etc which kids enjoy reading by themselves. Because children are familiar with most of the initial crisp summarized versions, they enjoy reading this type in simple lucid style and it automatically enhances their language ability.

OUR HOME LIBRARY (PART I)


Books are indeed a fascination that draws us like junkies…

Once into a bookstall, we seldom feel like coming out…

That’s the basic nature of book lovers.

Anybody who is interesting in reading would naturally have their own personal taste and my experience shows it’s the same with kids as well. I personally feel that the best way to kindle reading habit in children is to facilitate them to select books of their choice and help them understand the meanings or explain only when they seek help from us.

Simply let them enter the ocean of books and see them getting equipped all by themselves.

CUCKOO AS OUR ENTRY POINT TO ORNITHOLOGY


Kuoo..kuoo..Cuckoo..cuckoo..???

It was Friday. 

The day started as usual.

My elder daughter went to fetch the milk sachets and daily news paper. She loves passing through the kids supplement in the courtyard itself.

As she started to read the children’s page, we heard a feeble moaning sound.
Initially we thought it’s our younger fellow sobbing for being late or for having missed her chance to fetch the kids’ magazines afresh.

We went to her. But it was not her!

By then, lots of crows were making a gala show above our roof!

My kids rushed outside. They saw that all these crows together were violently scaring a poor bird. 

As my kids yelled, I went out. The crows gradually tuned into silence and finally left.

As we looked on, the poor frightened bird fell down the roof. 


My elder girly ran quickly and sat near the bird observing it. She felt very sorry for the bird.

As I took some water she ran and got a dropper and gave it with so much of care and passion, into its beak. 

Now the bird crawled and groaned. Slowly, it vomited something. She gave water for a second time. Once more the bird vomited. It repeated until the bird became comfortable.

 Now all were relieved.

School time got already over. Another day of absence!

I said it’s a koel and it would have tried to harm eggs in a crow’s nest. Else it would have tried to replace crow eggs with its own. The crows might have observed the act and hence the hungama.

She already knew all that!

She said it’s a female koel and that the males who visit our homestead sing sweet. Grandma had told her many stories long back!

As the koel remained in silence, she left us to care for the bird and went in to check the shelves for books on birds. She wanted to identify the bird with the images in it and know its nature and feed!

Now into the details gathered.

H&C Books has a small compilation (Rs.10.00) in Malayalam, on Birds- winged servants,(pakshikal chirakula sevakar) collected by Satheesan. It says about Cuckoo of family Cuculidae on page 21.Spotted cuckoos are females. Apart from sweet singers, they are brood parasites, eat lot of fruits and are good pest control agents.
  The Wonderful world of birds (Pakshikalude Adbuda prapanjam) is an excellent handbook for children, a preface for bird watchers. It is priced at Rs.90 and published by KSSP. 

A popular bird watcher and writer with the pen name Induchoodan, Prof. K.K.Neelankandan was former Principal of Brunnen Collge, Talassery. He is also founder member of the Kerala Natural History Society.
From page 32 of this book, we understand that Cuckoo is known as Indian koel. Scientifically it is named Eudynamys scolopacea. These birds cannot built nests by themselves nor take care of their young ones without help of crows. So these birds are seen wherever crows are popular.



        Further the page facilitates kids into watching birds for the difference in appearance due to gender, and continues the effort through many questions like why they became parasitic? Can’t crows identify koel eggs? And so on.

Common Birds, a book in the series India- the land and the people; by Salim Ali and Laeeq Futehally, from National Book Trust sketches the life habits of Cuckoos on page 72. (Plate 10.51)

It says Cuckoos are world wide in distribution. Males are glistening metallic black all over with a striking yellowish green bill and blood red eyes. The female is brown, spotted and barred with white. Only males can sing!
 
They are basically arboreal and feed on figs, berries, insects and hairy caterpillars. These birds are called Kokilas in Hindi and Kuyil or Pullikuyil in Malayalam.

Ornithology is the study of birds. This was popularized by Dr. Salim Ali (1896-1987); who is accredited as an authority on Indian birds, internationally.

 Those who are further interested can peep into his compilation entitled “The Book of Indian Birds”, published by Bombay Natural History Society. (ISBN 0195637313). It’s like an encyclopedia on Indian birds and an excellent field guide for bird watchers.



 
Plate 33, narrates the habitat of these birds as lightly wooded country sides, gardens, groves and cultivated areas. On page 179-180 of the Centenary edition, field characters are described vividly. We understand that koels are silent during winter and become noisy with onset of summer. They represent indicators for change of season.

Our Pullikuyil was silently lying down on the ground.

We were trying to search for the biography of this great scientist and ornithologist, when our fellowmen came in to gather donations for the upcoming temple festival.

 One of them asked for the bird. 

My kids were reluctant to part with the bird then. They didn’t want to cage the bird either. When asked why, they surprised me by reciting a verse taught by Grandma:

ബന്ധൂര കാഞ്ചന കൂട്ടില്‍ ആണെങ്കിലും 
ബന്ധനം ബന്ധനം തന്നെ പാരില്‍...
They സൈദ്‌: "Let the bird totally revive and fly off". 
But the visitor promised to take care of the bird and tried to catch it. 

The bird that lay for more than an hour now struggled and managed to fly onto a nearby branch. From there it flew still higher after sometime. It remained silently there for two days and then went off.

We thanked God for the fortuitous instance to save a life and the opportunity to learn from nature…

CHICKEN POX EPISODE- A MONTH’S TURMOIL FOR CHILDREN


It was Tuesday

My elder daughter came from school very tired. She simply put off her bag and without even changing her uniform, quickly climbed on to bed. 

That was never her nature. So I wondered whether it was something that has disturbed her emotionally.
After helping my younger one with her toiletry, dress change and lunch, I sat with her and poked deep in expecting something sensitive an issue that might have troubled her sister. It was a futile exercise. 

My elder one had already fallen into deep sleep. She woke up after 3-4 hours and still bore a tired look. However, apart from that look everything else was fine.

This repeated again on Friday evening. 

She took rest during the weekend, skipping her hobby classes. It was again quite unusual of her.
Sneezing all morning, I was right behind checking whether she took her medication for allergic rhinitis. She was so keen and had not skipped her medicines.

 However, she was back on track by Monday morning.

She is underweight for her age and immune challenged too. So, I was gradually getting worried.  
As far as routine went undisturbed, I controlled my anxiety. (All Mammas are over anxious after all!!!)

On Wednesday afternoon, as soon as she came home, she said: “Mamma, look I have some small spots on my chest. One of my classmates had chicken pox last week and he had come to school before total recovery. So teachers had retained him in the staff room and I had to be with him as I was late for the assembly. Is this how chicken pox starts, Mamma? I am getting frightened. Because my classmate had brown scars all over his face and hands. Another of my classmate, who shares my desk, had said all her body was itching yesterday and so she took the vaccine today.” 

Oh God, poor girl, she has just completed her usual self declared vacation due to cold intolerance that triggers discomfort during early morning hours with a combination of dry cough, sneezing, running nose etc. How she would make up this term? My thoughts went thus…

With prayers, we immediately consulted our family doctor. He asked whether she has fever and body pain. He further asked whether the spots are watery blisters or reddish small ones. Whether it was itching or irritating in anyway? No; not at all. Then maybe some skin allergy; anyway let me see for myself, he advised.

 At the sight of the very first spot, he certified: “Its chicken pox. There’s nothing to worry. It’s better that she got infected now; it would help boost her immunity! Now she need not worry of a chicken pox amidst public exams. It is more severe in adults than in kids. Let her have the medication and take rest. Put her on a low diet and don’t bath her until it subsides totally;” doctor advised.

INITIAL BLISTER
WATERY BLISTER
 There were only very few spots; maybe 5 or 6; that too quite small ones. No fever, whatsoever. As for the early morning sneezing, it was already usual with her.

 “Can I effectively prevent spreading by vaccinating my younger one?” 

Doctor said: “Elder fellow was exposed to this and she was carrying it since few days. As she sneezed and coughed during these days, she has already spread the virus unknowingly. If the younger fellow is infected, she would show symptoms soon or within 21 days. [Incubation period for this virus is 21 days.] Same is the case with all others at home. Those who gain immunity would escape from the infection. Those who have had it earlier also may escape unless the virus is a different strain.

Usually the care takers have a severe infection. Getting vaccinated or isolated after prolonged exposure is futile.

 Homeo practitioners say they have a preventive medicine; but, if you are infected the incubation period are up to 21days; you will show the symptoms within the period; even if you take the preventive Homeo medicine. 

As for the vaccination, it is valid only for 6 months. No use advocating a vaccine after getting exposed. It’s costly as well, ranging from 1200-1500 INR.”
INITIAL REDDISH SPOT
SORE LIKE BLISTER
 I continued to raise my doubts. 
"Can I send the younger one to school? She has been exposed for few days, already.”

Doctor replied: “You can refrain her when she expresses any symptoms like sneezing, cold, cough, fever, headache, and vomiting or body pain. Else she should have popped blisters. Until then she can move out.

Usually others who have caught the infection would start expressing the symptoms by the time the initial diseased person returns to normalcy. By the time the first fellow recovers, has her bath and starts going to school, the younger one might succumb to the virus.  

Generally it takes 10 to 14 days to express or if she builds up immunity she would escape from the infection. Let’s wait and see.”

Should I isolate and shift her residence?” I queried.

“You have had a long exposure. Initially the virus spreads through air as the suspected person coughs and sneezes. So no use isolating yourself now. During last stage, the virus spreads through touching the lesions and the oozes.”

After buying the prescribed medicine for antivirus, I purchased some tender coconuts and went home. 

I browsed and gathered all available details. I don’t know whether there is scientific truth behind all this or whether all of them are traditional home remedies. Anyway, I took the risk and followed most of the recommendations, which were effective on my daughter. Hence it inspired me to blog on the topic.

Patient was initially isolated from the moment she was identified with chicken pox. A well ventilated room that was live during morning hours, where I could always pop in was selected. 

Next day she had headache and then gradually body pain set in. Blisters started popping out on the head, face, neck, upper arms, palms, back, thighs, etc. 

LESION
 Diet went as follows. 
(Nutrition experts are most welcome to rectify mistakes if any and suggest additions available. Kids always prefer variety.)

Generally an easily digestible, vegetarian diet, with lot of fiber, fruits and vegetables is recommended. Avoid all oily items, junks and fast foods.

Breakfast: Idli with sambar or coconut chutney; Bread with stew or jam or cheese.
Snack: Oats as porridge in milk; cornflakes in skimmed milk.
Tender coconut (1)
Lunch: Unpolished broken rice porridge with green gram or green peas alternated with Basmati rice mixed with green peas or carrot as a sick man’s special pulao!
Skimmed milk curd or butter milk 
DEVELOPING RED SPOT
  Clear soup made with carrots and fresh coriander leaves or celery leaves and small onion or amaranth leaves and onion. These were spiced with black pepper, cumin, coriander, garlic and ginger.
Snack: plain fruit salad (mix of all fruits available- banana, apple, oranges, papaya, watermelon, strawberry and a chickoo)
Tender coconut (2) or a drink of protinex, pediasure or nurture (protein powder) which she disliked, but still managed.
Dinner: Aappam (fermented flour with yeast) or Nice Pathiri and vegetable curry of carrot, green peas, etc.
Snack: vegetable salad with onion, tomato, salad cucumber, capsicum and green leaves like lettuce or broccoli or Chinese cabbage.
She drank lot of water to prevent dehydration.

CRACKED LESION
 In 2 days, more spots got scattered all over her body, as if it is a design on a plain cloth. As the blisters became watery and big, itching set in. She couldn’t wear any dress. Now, I gave her frequent sponge baths with warm water (a bowl) mixed with baking soda (1 tbspn) and crystal salt (a handful). During first few days, this was repeated once in 1 or 2 hours and she said it lowered her itching a great lot. I also used lacto calamine lotion (with Aloe Vera) and it soothed the sores, she said. Boiling the towel after every sponge bath, with a cap- full of Dettol was also done. 

The blisters appeared in series, as one batch crops, becomes water filled, forms lesions, slowly dries and leaves a scab; another would have cropped up…We can see all stages of the blister on a persons body during a week. Spot-blister-lesion-crust-scab-scar-are the different stages of the pox…As the blisters formed, she had difficulty to sleep properly and so she slept in breaks during the morning hours also. First week kept them tied to beds. 
CRUSTS - DRYING LESIONS
 Second week made them more irritated by boredom unless engaged. Fever and itching subsides. But they are kept isolated and not permitted outdoors either. Absence from school and all activities naturally bores them. Eyes are paining for some, so reading is not easy. Neither is watching television. 

So, I gave her all her toys, story books, kids’ magazines and indoor games. Kept of all her books and school materials! 

After few days, she started watching television also. However, I disinfected all her toys and games by exposing them to hot sunshine hours for days repeatedly.

In 5 different crops, she totally had 140 spots, apart from those on head. Doctor said it’s a mild infection. There would be more blisters otherwise.

 After two weeks, all blisters started drying and in another week all became scabs and later scars in 21-25 days. Some of the spots in the last crop didn’t develop into blisters but dried up as it popped.

FINAL SCAR ON SKIN
 When all fell off, by itself, she had her bath. Now the patient is ready to move outdoors. It was a month of turmoil by then…

On the 10th day after I saw blisters on my elder, my younger one had a dry cough and throat pain and was given expectorant. She opted steam inhalation for smooth breathing and gargled salt water for relief of throat pain. After 2 more days, she had a viral fever with severe body pain and was administered with antipyretic and analgesic. After 2 more days, spots were visible which popped out after one more day. From this stage, she was given anti viral medicine. She had spots inside her eyes also for which she was given an eye drops and eye ointment, to be applied @6times a day for 3 days.

On my younger child, spots were spread more uniform, covering all parts of her body from head to under her feet. The blisters were huge and some were pus filled. It was less itchy. However, she had severe fever for more than a week. The last crop took more time to crack and dry. She had about 194 spots in all. On her I tried sponge baths with water mixed with vinegar (1 cup vinegar in a bowl of water) and she was comfortable with 1 or 2 baths a day.

PUS FILLED BLISTER
 Apart from changing her bedspread, towels and dress materials daily and washing them with antiseptic liquid; I also ensured that they are sundried for long hours.

 I gave her warm water for toiletries and used disposable paper plates and cups. When ever she was near the young one, I gave them disposable masks to cover their mouth and nose and disposed them too. Wet baby wipes or soft napkins were used to clear the blisters which broke during wake hours and these were also properly disposed.

It is said that Chicken pox spreads through air; as we sneeze or cough. Once the blisters start to crack open, they spread through touch also. Hence it is better to avoid sharing of utensils, even combs.

A Homeo medicine that soothes skin of scars completely is available. A liquid formulation for internal administration, it’s a bit bitter. 

An ayurvedic cream now available under the trade name Cutis is also said to be equally effective as topical application on skin. Manufactured in India by VASU Healthcare Pvt. Ltd; an ISO 9001 company, It has a good smell and kids willingly use them. (www.vasuhealthcare.com or Helpline 0091-265-2644459)

 Home remedy recommends application of an herbal paste made of neem leaves and Kasthuri manjal, variety of turmeric rhizomes, soaked and peeled overnight.

Spreading neem leaves on the bed of the patient reduces irritation and itching.

In total, kids have to be retained for a month indoors; under proper care. They take a week or two to overcome fatigue and fall back to the usual routine.

Amidst their convalescence or soon after, depending on our immunity, the caretakers also succumb to the virus…

In adults, as said, the infection is more severe; with recurrent fever, headache, body pain, and far more number of spots, sometimes big ones, that too spread all over making an ugly rather devilish a look! 

It’s more aggressive on oily skin, and in parts with suntans.  It is said that for some, blisters occur in mouth and food intake is hindered.

The onset of the disease has many variations, the pain or discomfort also varied with individuals and the process of healing also was different. While my elder had high extent of discomfort and was not at all feverish, my younger one was more feverish and had less itching. While the sores in my elder dried at a faster pace, it took more time in my younger.

Once the whole process of chain infection is complete in the family, its better even to paint the house and disinfect all furniture and utensils, even television remotes and keyboards!

Taken on a positive spirit, this is a real break from routine life and cleanses our system with the special diet and adequate water intake. It makes us more health conscious as well. The only disadvantage is the loss of productive work hours and man days. It’s an era of inventions. So, let’s hope better preventive mechanisms become popular soon.

(Please do share additional tips and experience if any on chicken pox infection; its cure and care.)

SUDOKU - learning and playing the game


I have two kids and both have highly diverse interests. So, each is enrolled for extra curricular activities, in different places. As the session is in progress for one, the other remains with me and during the waiting hours, both are keen to play games on my cell phone.

I seldom use the instrument except to send an urgent SMS or make an emergency call when out of home. But these young fellows, they have identified other options and speak about them!

In my Nokia 2630, Sudoku is an available option in the games folder.

One day as my younger one played with the same, I simply peeped in. I felt there was something wrong in the way in which she moved ahead in the game. I got the cell, read the instructions and tried playing the game. Wahl!my trial was successful. We got an emoticon displaying CORRECT!

My elder kid was already familiar with the same as she used to play it with her aunty. Though she can play for herself, she could not explainthe basic points to be considered and hence couldn't guide her sibling effectively.

Earlier my younger one thought it was something related to Mathematics and so kept herself off, as she is yet to learn addition and subtraction. however, as she came to know about it, she has become so interested that she is quite eager to fetch the morning newspaper and search for Sudoku in it.Though its a higher level, she facilitates me to fill in as much as I can. She verifies for the answers where available and gets excited for all the right entries.
There are small books with Sudoku puzzles for kids in any book stall.

 What is a Sudoku?
It is a logical number placement puzzle in which we enter a digit from 1 to 9 in each cell of a 9x9 grid made up of 3x3 sub grids, starting with various digits given in some cells. Each row and column must contain only one instance of each digit. As we enter into the game option, there are three categories, Easy, Medium and Hard. The basic procedure is the same.

Naturally I took the Easy segment. There were 100 puzzles in that alone.

Easy simple grid:
The first one was as tabulated below.

This game is like filling up the blanks. The numbers used in this grid ranges from 1 to 6. Now I named the cells based on position in the rows and columns for identification.
R1 C1
R1 C2
R1 C3
R1 C4

R6 C5
R6 C6

In Row 1, only RIC2 was blank. The missing number was 5 in that row. All other numbers from 1 to 6 were present in other cells. 

In row 3, only R3C4 was missing and the left out number was 4 and in row 4, the missing one was R4C5 and the value was 1.

Similarly in the last row, only R6C5 was missing and the missing number in that line was 4.
This seemed so easy.

In the remaining two rows there were two cells each with missing values. How to find that?
I calculated the total sum of all values in the complete rows and columns. Both ways it was 21.
Now I started concentrating attention into columns. Last column had only one left out value. Cell R2C6. The number was 1.

In the 4th column the cell was R5C4 and the value 3.

Addition of all values in every row and column gave 21. Thus the Sudoku was completed and the answer was right!

So, this is how we play a Sudoku? The number range would differ and also the sum total also with each Sudoku. This is only demonstration of a simple one for beginners.  

This helps kids to learn through fun. It helps them to identify missing numbers, addition and subtraction. It improves their comprehensive ability, concentration and confidence. Read more about Sudoku and its logic, mathematics, variants, etc at: http://en.wikipedia.org/wiki/Sudoku

Standard grids:
Sudoku is generally in a 9x9 grid format in which the sub grids are units of 3x3.

Naturally the sum of numbers 1 to 9 along a row or column would be 45.
In columns C3 AND C7, only two numbers are missing.
In C3, the numbers 2 and 7 are missing. In R6, we have 2 in C5. So the probable value for C3R6 is 7.
In C7, the numbers 1 and 3 are missing. Here also, in R4, we have 3 in C6R4. So the most probable entry here is 1.

Now let us move to rows.
 In R1, R2, R4, R6, R8, R9 only two numbers are missing.
R1: here 1 and 7 are missing. But number 1 is available in C9R3 and number 7 in C2R2.
So it is easy to note the numbers here.
R2: the missing numbers are 1 and 5.
Here again 1 is already available in R3C9 and 5 is available in C6R8.
So it is easy to note the numbers.
R4: the missing numbers are 2 and 7.
The number 2 is already available in C8 and 7 in C9. So entry of numerals is again an easy task.
In R6, the missing numbers are 1 and 4.
Of this 1 is in C2 and 4 is in C1. So again numbers is easy.
In R8, the missing numbers are 3 and 6. Here also 6 are there in C4 and 3 in C1.
In R9, the missing numbers are 1 and 7.Here again 1 is already there in C1 and 7 in C8.
So the entry is quite easy.

At this stage let us move to columns once again. As we span them, we can see that C1, C2, C8 and C9 have only one missing number each. So, let us fill them soon with the respective missing number from 1 to 9. (Entries are highlighted in yellow).

Now rows R3 and R7 remains to be filled. So let us move back to rows.
In R3, numbers 4, 7, 9 are missing. But 4 are available in C4 and 7 in C6. So let’s enter 4 and 7.
In R7, numbers 6, 7, 9 are missing. But 6 are in C4 and 7 are in C6. So let us enter these numbers 6 and 7.
These entries are highlighted in blue.
Now we can enter 9 comfortably in C4R3 and C6R7. (Entries highlighted in green.)
The only box that is left blank is R5C5, waiting for another 9.(entry highlighted in pink).
This completes the Sudoku.

There is another method of approaching the same Sudoku through sub-grids. This is elaborated in the link http://www.sudokudaily.net/instructions/ . Here we can also play Sudoku online, daily at different levels.

In this Sudoku,let us combine all available options.This is a sample from the Nokia category Hard(level1).
Initially let us divide the Sudoku into sub grids of 3x3 units.(Better use a sketch pen to demarcate thus in the beginning.)
In each sub grid the numbers 1 to 9 can appear only once.As earlier, in any column or row also, the numbers 1 to 9 can appear only once.
Now, let us start the process by identifying the column or row or sub grid that has least number of blanks and start filling them one by one. As we proceed, we can see that the rows or columns with many balnks are reduced to minimum blanks and are automatically easy to be filled in.
 
The resolved puzzle is added for cross reference...
