My son is 4 wks old today and it seems like every night for the past 2 weeks or so he is colicky from 10pm-1am. It doesn't matter what I do he won't stop crying. Sometimes I am able to get him to stop crying for a little bit, but then he will just start back up again. I am a first time Mom, so this is all new for me. My husband went out and bought the Enfamil Gentlease formula since we were giving him the newborn one. We thought maybe it was gas causing him the discomfort, but so far it hasn't made a difference.
He might be dairy and soy intolerant, lots of babies are. You can check with your ped and see if they have other formula samples, our doc office has lots of good start and nutrimagen samples. My sister's 2m old baby has gerd and food sensitivities to dairy, soy, and peanuts.
Our son will be 3weeks old tomorrow and we just went through something similar. For the first week and a half he was taking the Newborn Enfamil just fine and sleeping for his usual stretches of 3 hours or so he was already on a pretty good schedule when we brought him home because he was in the NICU for 6 days after his birth, and they run a tight ship when it comes to feedings. One day last week he just woke up screaming, something he had never done before we thought he was just wet and my MI swears we are spoiling him. From that day on we could not lay him back down flat on his back to sleep. He was constanly making this thoat clearing grunting sound and turning bright red. We ended up taking him to the ER last Saturday because he had milk coming out of his nose and spitting up clear bubbles for 2 days straight. We were told he has reflux something very common among little ones. The sphincter between the esophagus and the stomach is immature and allows for stomach contents to flow back up...no beuno when it's straight stomach acid. We swiched his formula to Enfamil Gentlease and we have been feeding him sitting up and not so laid back in our arms to help everything stay down and we also keep him up right for at least 30mins after every feeding. This routine makes feedings longer for us but for the past week he has made such a huge improvement and no more milk out the nose o bright red faces.
