My 3 week old sleeps with her mouth open sometimes, I’ve noticed it’s when her nose is a bit congested!
Same her nose is bit blocked too
My little one always has her mouth open, catching flies😂 I think she gets it from my husband as he is exactly the same😂
Mine does this sometimes. Usually when they’re sleeping upright on me. I just gently push under the chin up to close the mouth and she usually keeps it shut then x
@Alannah yep this is my little one and partner too .. both noisy as hell and sound like truffle pigs
@Ashley exactly! All fun and games until it’s 2am😂😂
My girl sleeps with her mouth open most times as well though 😟
