hello ma'am...my son is 11 year old and his height is 5'3 and weight is 80 kg.....is it normal

A. Namaste Mom, The weight for his age is quite on a higher side, observe his dietary habits, commonly kids around this age tend to lean more on unhealthy junk foods as such . also make sure bakery, sugary and processed foods are controlled and involve the child in some form of physical activity such , like outdoor playing , swimming ,cycling , sports etc
