Sounds normal maybe dreaming but keep and eye on her and if anything concerns you you can always call her dr
It is normal for her belly to expand so much when shes sleeping? Im watching her and she breaths so heavy and fast and has a whistle sound when shes knocked out i suctioned her noise but nothing came out
Yes it is perfectly fine it won't affect her at all :)
Might be dumb im a first time mom and i have no idea
