Child Growth
Child Growth
At birth, the baby will weigh about 3 kgs. After this, the baby will lose 150-200 gms in the first 3 to 4 days. Then, there will be a rapid growth and gains about 25 to 30 gms, a day for the first three months and little less after that.
The widely accepted formula that a baby doubles his birth weight at 5 months and trebles it at 1 year may be misleading. A smaller baby of 2 to 2.5 kgs. at birth may be 4 times his birth weight at 1 year of age.
The length of a baby at birth is 48 to 50 cms., and at 1 year of age he becomes one and a half times that size, and there after increases as shown in the table below:
The average increase in weight and height during the first 5 years :
| Age |
Weight increment per week |
| 0 to 3 months |
200 gms. |
| 4 to 6 months |
150 gms. |
| 7 to 9 months |
100 gms. |
| 10 to 12 months |
50 to 75 gms. |
| Per year 1 to 5 years |
2.0 kgs. |
| Age |
Length increments per year 25 cms. |
| 1st year |
25 cms. |
| 2nd year |
10 to 12 cms. |
| 3rd year |
7 to 9 cms. |
| 4th year |
6 to 8 cms. |
| 5th year |
6 to 8 cms. |
You should remember that these are averages, and all babies will not conform to this pattern. There is a wide range within which a baby’s growth is considered normal.
The average weights of well-nourished Indian children at different ages are as follows:
| Age |
Boys |
Girls |
| Birth |
3.0 kgs |
2.9 kgs |
| 6 months |
7.5 kgs |
7.0 kgs |
| 1 year |
9.5 kgs |
9.0 kgs |
| 2 years |
11.7 kgs |
10.6 kgs |
| 3 years |
13.6 kgs |
12.6 kgs |
| 4 years |
15.0 kgs |
14.3 kgs |
| 5 years |
7.0 kgs |
16.0 kgs |
The above weights are 1 to 1.5 kgs. less than the weights of American children, probably because of racial and ethnic differences.
The average heights of well-nourished Indian children at different ages are as follows:
| Age |
Boys |
Girls |
