Baby had jaundice during pregnancy.

I was married young and husband use to beat me during my pregnancy and before that also since the time l got married. Consequently, l couldn't take proper diet and suffered a lot, proper treatment also couldn't happen because lack of money and other issues at home. I had my first child at the age of 23 or 24, he suffered from jaundice when he was in my womb. Also, the umbilical cord got stuck around my child's neck at the time of pregnancy. Chief complaints : - Ganesh ( 8 years ) doesn't feel like eating anything. - 2 to 3 days pass by, but he won't demand food. - He weight is extremely low. - He looks malnutritioned. - Also, he gets skin allergies (rashes) whenever eats anything sugary. Please, suggest guidance in to this matter specifically on diet that can be given to Ganesh. Any health supplements to cure the prevailing conditions.
