my son almost 4 yr 6 months is gaining weight very slowly since he was 2 yrs old, his weight is only 15 kgs now, and is very slim. should i worry, his eating habits are good and stomach also fine.

A. dear parent, a weight of 15 kg is a normal weight for ur child at the age of 4 years 6 months. also if ur child id active, playful n achieving all growth milestones then it indicates good health.
