hello my son is 3 year 8 months old.. his weight is 13.6 kg.. is his weight is normal according to his age?

A. By the age of three a child should be around 14 so little underweight your child is your child should be 16 by the age of four currently I would recommend you to give more of proteins they’re going to be beneficial in the growth age of your child you can opt for both veg and non-veg protein
