Why my 1 year son is not growing ?

Gee this type of question is extremely difficult to answer for anyone even a trained medical professional. Your country, KUWAIT has pretty good relations with us AMERICA. My advice to you is to seek professional help at one of our military bases there. Maybe they can help directly or refer you to some one that will help you. Your country is very wealthy and should have plenty of the support you need. If for any reason you cannot afford medical istance contact the "International Red Cross" or "Saint Jude Hospital for children" in AMERICA. "Surf" the Internet. God bless you and your child.
