Gassy 5mo baby up alllll night

Traci • Momma to Irie, Tavian, Rowen & #4 Due June 3, 2018

My baby is 5 mo old. He has never been real gassy, but the last couple of weeks, after I feed him, he wakes up with gas pain. It's usually an hour after a feed (bf) I feel like he would sleep longer if he didn't get the upset belly. He doesn't do this in the morning, or during the day. He does get bottles of pumped milk during the day while I work.

I have tried gripe water, which does not help. I'm desperate for some sleep, and for him not to be in pain. First we went through a sleep regression - which has never stopped- and now this.
