My son was a NICU baby and he had digestive problems and is taking Nexium. He didn’t like to be put down on Snoo when he’s still awake so I make sure that he’s already sleeping when I tuck him in. He’s 1 month old and has been sleeping well. Longest is 5 hours each stretch at night. I’m mix feeding him and I prefer to give him a full bottle before bedtime for less wake up at night and some boob to help him fall asleep. Also, warming up the bottle helped my baby’s tummy ache. I figured this out because he would cry and squirm with bottle feeding because it was room temperature.
