baby is birth weight was 3.8 kg . now she is 7 months old.her weight is 7.2 kg. she is eating 3 times and satisfying amount. why she is not gaining weight

A. Looking at the birth weight by the age of six months of child should have been somewhere on 7.6 KG so your child is actually quite underweight for that matter right now and you are mentioning the child is eating well still I would recommend you to go ahead with giving more of dairy products and vegetarian protein to the child
