My baby is 3 months old and recently she has been rolling over from her back to her stomach in her sleep. The thing that worries me is that she doesn’t keep her head turned to the side so she can breathe. She has her face literally planted strait faced down onto her bed. I keep turning her back onto her back but she keeps turning over to her belly with her face flat onto her bed. So I’ve tried moving her head so her head is sideways but she immediately puts it back strait. What worries me most is that she doesn’t know how to roll over from her belly to her back yet. She only does it from back to belly. Any advice please??
