Top lip

Sarah

My baby has been ebf for 3 weeks now. He has been tucking his top lip. It’s not necessarily painful but I think it’s making him gassy. Any tips on fixing it this? Also he wets tons of diapers but only poops every 3 days or so. Should I be worried? His appointment at 10 days after birth he was at his birth weight so I think he’s gaining still. Any advice?
