I think DD2 can’t/won’t breathe through her nose. It doesn’t seem to cause many issues, apart from snoring like a bulldozer and quite a bit of dribble, but would you get it checked out?
We’ve also realised it’s probably the reason she says ‘n’ instead of ‘l’ because she seems to always talk like she has a blocked nose. She can blow her nose pretty well when she gets a cold, but doesn’t seem to breathe in through it.
So what do you reckon? Try to get an appointment at the GP after the holidays? Or just wait and hope it goes away?!
