my baby looks soo slim, he is 6.3 kg now and birth weight is 2.7 .his weight is good? how I feed him to get chubbyness.

A. hello baby weight according to birth weight os gpod enough and absolutely nothing to worry about.. some babies can also be slow weight gainers and if the baby is active then weight is not a problem and make sure to give your child healthy and nutritious well balanced food in the diet
