I have 2 sons they are older now teens and young adult on #3 boy definitely needs to burp hold him higher up on your chest and pat his back a little harder,stretch his legs like a bicycle so he won't have issues #2.or lay him on your knees and pat his back ,,usually being held higher up on the mom helps try it
I've tried sitting up, laying her down and supporting her head, tiny bounces, rubbing her back, patting her back, sitting her up and leaning her forward to burp. I've tried everything everyone has told me and nothing's worked just yet. @rhia
