My son is 1 year 10 months old and he is not gaining weight. His current weight is 11.8 kg. What should be given to help him gain his weight?

A. But Why do you need to give anything extra to the child when your child is having an appropriate weight gain I don’t think so anything extra is required because I think the way you are feeding your child is quite appropriate which is why your child is having appropriate weight as per the age
