Say baby Aryan weighs 9.5kgs at 10 months-that means he’s in the 50th percentile, so 50% of 10-months old babies are smaller than him. And 50% are heavier. The same goes for height and head circumference-the gray area above or below Aryan result (where the majority of babies fit) shows what percentage of babies are bigger or smaller, taller or shorter than him.

Babies all grow at different paces. The growth chart calculates average from given data so there’s no need to worry if your baby is not within the percentiles as longs as they’re growing steadily. If you are concerned about your baby’s growth, we recommend you put your mind at rest b visiting a healthcare professional
