@Sophia yes we have tried that !!
Might be formula/ breast milk problem. Might have to switch. Also could be a tongue tie or something causing extra air to get in. That’s physical. I’d get a lactation consult and see what they recommend. They usually are more helpful than doc. Mine had a tongue tie.
@Pauline b yeah I let them know but they said it’s too soon. Let’s see
Have you tried sitting them up right for about 15-30 min after feeding? My doctor recommended that to me and I noticed she doesn’t spit up as much anymore!
