My son is 2 years old now but it’s weight is not as per his age and his not taking any food properly so please suggest the foods for his weight gaining.

A. hi dear When growing kids don't gain weight as they should, it is called "failure to thrive." Failure to thrive is not a disease or disorder itself. Rather, it's a sign that a child is undernourished. In general, kids who fail to thrive are not getting enough calories to grow and gain weight in a healthy way.
