hi sir actually my son is 2 years old, he is eating good but he is not having enough weight, guide us how to improve his wait.

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.
