Dear Doctor, I am a first time mother.My baby boy is 3 weeks old and was born with a jaundice and was admitted in neonatal ICU for 4 days on ow blue light. I am breastfeeding and am topping up with Nan optipro 1. My baby doesn t gain weight, also he keeps on demanding for food but has got difficulties feeding, he will get restless while feeding until he stops. He will keep on demanding but you can tell he stragglers. His stomach get big and tender and he struggles to pu. He vomits almost every nightime and will rest after that. Please advice,
