Hello Doctor, My son is 22 months his weight is 8.5kg, and he is premature baby and when he was born his weight was 1kG. He is eating rice, milk, fish, meat, apple, banana all the normal food and also breast feed but he can not eat egg white because of allergy. My question is his weight is normal according his birth and age because every body is asking why his health is so thin? Please advise me what food I will give him so his weight can gain.
