Sounds just like my son when he was about that age. He was a NICU baby and learned to eat form a bottle so I gave him breast milk thru a bottle but also had to supplement with formula. It was so frustrating to see him in such pain. We used Gripe Water which didn't help with the gas too much but as a side affect got rid of hiccups. We also started giving him gas drops at every feeding and halfway between feedings (up to 12 times a day is safe). I believe that helped. We kept him on the drops until he was about 6 months old - he is now 7 1/2. We also changed his formula from Enfamil to Nutramegin. It was expensive but it helped out tremedously. He stayed on that until he was 5 months old and then we transitioned him to Enfamil Gentleeae. He is doing great - really chubby and really happy. It is very hard to see them in such pain, but more than likely it will pass once his digestive system matures. I hope this post helps. Feel free to contact me with any questions.
