#asktheexperts my baby boy weight 3kg at birth..and he is 16 month and his weight is 8 kg and his height is 76 cm...should I worry..,?

A. You should be concerned about it because if I only go by the calculation of three times of the birth weight at the time of 12 months it should be nine and right now it should be at least 10 kg a child is lagging behind in the way you should check with your doctor once
