Hello, my baby is 3 days old. He born on 36th week of pregnancy and his weight during birth is less than 2 kg. Doctors have kept him under observation. He is been given antibiotic for respiratory problem. Now doctor has informed that the baby's stomach bloat after milk. Motion and urine is alright. They have suggested for further care under Neonatal ICU to understand the issue correctly. What can be the problem? Any recommendations would be helpful.
