My baby is 3year 6 months old and he weigh 11.5 kg and height 95 cm . Is he underweight or is it normal. He had his heart operation at 5month old and he is preme born at 33 weeks weighs 2.2 kg

A. See in general standard your child should be somewhere around 15 kgs but since your child has had a heart operation and was a premature child maybe we can eliminate one or 2 kg but still the child would be underweight I think it would be better to check with your doctor and go for a proper diet plan which will help in increasing the weight of your child
