I have a nine week old baby boy that was born premie and in the NICU for two weeks. He is now fine except for feeding. He was not able to BF due to his hospital stay and we have had problems with formula. He pukes up most of his feeding, is always extremely gassy, very fussy, and hardly ever sleeps. And when he does sleep it is for very short periods of time. The doctor has switch his formula twice already from Enfamil Lipil to Prosobee and now we are on Lacto Free Lipil. What else shoudl we try?? This is my third baby but the first one that was not mostly BF so I do not know else to try? Any suggestions would be so helpful.

Thanks Jenn
