Sleeping with mouth open

My baby does this , was told to close her mouth . As baby shouldn’t be breathing through the mouth .. not a clue xx

My son sometimes sleeps with his mouth open too, but if i feel he is still breathing out his nose. I think he is just like his daddy and catches flies in his sleep 😂

My baby is 8 weeks old and still does this - lactation consultant told us it’s because her tongue is big! As she’s grown she’s started closing her mouth a bit more but still mostly open and when we close it she just opens again. Has he done it from birth? Could be a similar thing but maybe worth getting HV opinion x

Babies don’t know how to breath through their mouths. Even if they sleep with open mouth they are breathing through their nose

I thought the exact same because sometimes I do feel a bit of air coming through his nose whilst his mouth is slightly open.. however it's still concerning 😟

thank you, yes, not as much since birth but justlast week I've noticed it more and more. I have his 6 weeks check in appointment next week Monday so will speak with the doctor and see.

I didn’t even know this was a problem? Is it? 🤷‍♀️
