Rolling to Stomach at Night

Sh

Sorry, I’m sure this has been talked about before. My LO has started to roll to her stomach in her bassinet at night. I don’t think she has a good control of going from stomach to back yet because she’ll fuss after some time has passed. I keep on having to flip her to her back. She lays there ok for a little and I know I shouldn’t be super worried about her breathing or anything (even though I am) but I’ve read if they don’t master stomach to back then I shouldn’t let her sleep that way. She also gets frustrated after awhile because she can’t flip back. Any tips??
