Hi doctor, My baby was born at 37 weeks due to growth restriction. His weight was 5 lbs 3 oz. He was in NICU for seven days due to low blood sugar. He is 7 months old and weight 11 lbs 6 oz. He had reflux issues and lip and tongue tie. It was fixed at two months. The reflux was fine after 5 months of age. Initially, he was also constipated for around three months. We started solids at 6.5 months of age, and it made his constipation much worse. He had a barium enema to rule out Hirschsprung, and he was not able to get all the barium out. He is not pooping and refusing any food. He freaks out when I try to nurse him. Doctors are saying it as milk protein allergy, but I do not believe so. What else could be causing constipation and failure to thrive in a breastfed baby? Please help my baby.
