My son is currently five weeks old. After birth he choked on amniotic fluid 3x and was sent to the nicu for 4 days. They noticed reflux type behaviors. He was hoarse, gargles, chokes, arches, spits up, very congested etc. our pedi started him on axid at 2 weeks. He spit up less but was still super fussy, arched his back, would gag on acid, and is a very noisy sleeper etc.
At this time I randomly decided to give up dairy bc I noticed he was much fussier when I ate pizza, lasagna and chocolate. I've been dairy free since the day after thanksgiving.
Baby boy continued to be super fussy, never relaxed, arching, congested etc. I also noticed that on occasion he has green stool and mucous in his stool. Somedays his stool is normal, others its not. He's miserable when he poops aboutnhalfmthe time. The mucous worries me but the pedi is not concerned at all.
I called my pedi again and he told me to switch him to Prevacid and to start a probiotic. He does not think its a milk intolerance and said they are super rare (didn't even test for it). Since starting Prevacid we have seen slight improvement (day 5). He is still super fussy, but easier to soothe for the first time ever. He actually goes back to sleep at night. He still cries a lot and looks pained though. However, for the first time ever he has sat contentedly for a period of 30 mins. My poor sweet baby has never been happy enough to sit contentedly for that long. It breaks my heart. He still occasionally gags on acid and has days where he is more congested than others. His sleep noises have decreased, but he still wheezes and gags occasionally.
Anyways, improvements, but not perfect. He's still not thrilled or happy.
Any ideas what it could be? Does it sound like reflux or an mspi intolerance? I feel like I'm missing something. It's heart breaking to watch.
I should add he eats very well and gains at least 1/2lb a week EBF. There is so much conflicting info out there on the Internet. I'm on a strict diet and if its not mspi I don't want to continue it.
Please help!

Re: Cross post-- EBF reflux or mspi or both?
If you accidentally mess up and eat something how long does baby react to it (after the one month mark I mean)? Does it take another whole month?
