7 week old awake 2 am and beyond!

My 7 week old son sleeps 7:30-1 almost without a fight. Then my husband feeds him, changes him and puts him back to bed.

Well he wakes again around 2, then 4 and finally between 5-7 wanting to eat. I finally skipped his 4 am feeding 🤞🏻.

Ideally he should wake between 6-7 for breakfast and start the day. I know he’s young. I NEED to break his waking habit from 2 am and on. I don’t mine feeding him at 4 and then back to sleep until 7 or 8 if he needs it. I cannot wake up every other hour. I formula feed btw.

He seems to get upset with gas or poops. He kicks up and squeals without screaming and crying but I can tell he’s uncomfortable. He’s on Zantac and acid reflux formula and mylicon. He’s been on this regiment since 3 weeks old and they’re proving to work well.

Anyone have any suggestions? My husband feeds him at 1 am and I’m responsible after that since he’s working and I’m not sleeping!!! 😭

Help!!!
