Your paediatrician will evaluate your girl periodically to see if she is following the common growth patterns.

Baby growth charts are important indicators of your child’s development during the first year. They help you and your paediatrician determine if your baby is growing normally. Most paediatricians refer to WHO standards for tracking the development of infants.

A baby’s growth is determined by three important factors: height, weight and head circumference. All children grow differently, but most of them follow similar growth patterns. Moreover, there are different baby growth charts for boys and girls as the growth patterns between them vary. Your baby’s measurements will then be compared to the average measurements of other infants of the same age and gender to see if he/she is following the normal growth pattern.

How to read a baby growth chart

The growth of your child is measured in percentiles. Percentile is a number that indicates where your child stands as compared to other children of the same age and gender.

For example, if your six-month-old son is in the 30th percentile in weight, it means that 30 per cent of children his age weigh as much or less than his current weight. This also means that 70 per cent of baby boys weigh more than he does.

If your five-month-old daughter is in 50th percentile, this means that 50 per cent of girls of her age weigh as much or less than she does. It also indicates that 50 per cent of girls of her age weigh more.

Should you worry about the percentiles?

Percentiles can be scary, especially when they are on the lower side of the average. Thankfully, percentiles are not your child’s report card. Just keep in mind that each child has his/her own growth rate. Your doctor will evaluate your baby periodically and will advise you in case there is, indeed, something to worry about.

How often will your doctor evaluate your child?

Most doctors follow similar routine, which is as below:

  • Evaluation at birth
  • Evaluation at first week
  • Evaluation at second week
  • Evaluation at first, second, fourth, sixth, ninth and twelfth months

Depending on your child’s condition, your paediatrician may change the routine. Make sure to follow his advice.
