It could be any of those 3 things but not your diet. my boy had the same problem but after changing the bottle nipple, inclining the mattress and only feeding him in an incline position he stopped. I also wait a little bit to move him if I’m feeding him on my arms
It could be any of those things. My baby doesn’t have reflux or anything but if I lay her down too soon after a bottle she will be sick. I aim for 30 mins where possible sitting up and it has reduced
@Gem i’m going to try pace feeding
Ever since i let my baby sit up after feeding her spitting decreased. Maybe it’s that
Are you pace feeding? To make sure you aren’t overfeeding?
