Are you formula feeding or breast? I had the exact same with my little one and she wasn’t agreeing with whole milk we have changed to goats milk and so far so good! Apparently goats milk is a lot lighter on their stomach and most similar to breast milk.
@MP she has a tongue tie, not a severe one. Seen infant feeding team today and they told me it’s not common practice to snip anymore due to some who study that said it has nerves and they don’t know what their damaging and unless I was getting no where they won’t do it
@Mills I’m breastfeeding .
We have the same and have been referred to do a snip of her tongue, as she has a tongue tie. Check whether your baby perhaps has the same and talk to your GP/health visitor. Tongue tie afftects their lach or look into reflux as that can also cause milk coming up. Personally I find it very stresfull as our little one chokes and its so scary! I hope you get ir sorted soon xxx
