someone told me mouth breathing is a problem as babies normally breath through their noses I didn’t know this and thought it was normal for babies to breath through their mouths my baby has had a snuffly nose since birth not sure if that’s why she’s breathing through her mouth she does breathe through her nose too but it always sounds blocked, and it’s never runny tho it’s always dry huge snots that’s come out I’ve tried saline spray and a snot sucker didn’t do much baby is 6.5 months
