My baby is four and half months old, he had Tracheoesophageal fistula repair right after his birth. As he was healing from the surgery doctors kept him from feeding for around 15 days of his birth. After that when they allowed him to feed he used to deny breatfeeding so we started to give him Nan stage 1. He has a huge vomiting tendency, I have read in many articles that once the baby with such medical condition starts taking little bit of solid food with water or milk the vomiting tendency comes down. Should I do this?
