I was told by my baby’s doctor to burp more often or between each oz then hold them up after a feeding for 20-30mjn and when they sleep to make sure their head is to the side
Does it smell vinegary? It might be the formula he’s not agreeing with also, we found on aptimil that he was super sicky and it stank of vinegar, we changed over to cow and gate and haven’t had any more issues! Still a bit refluxy but the milk change helped a lot
If you think it’s reflux, you can hold them for about 30 minutes afterwards and it should help a bit, that’s what I was told today by my daughters nurse
