New skill learned making bedtime anxious

[Pippinsqueak]

Not sure if this should go here or sleep. My baby is 4.5 months old and today has learned to roll over from back to front to her left. At first I was really pleased but now all she is doing us turning over in the next to me crib and getting stuck face down or face against the side. She hadn't learned how to roll back yet. I'm so worried she ll suffocate herself in the night. Has anyone got any advice/hints/tip/tricks/solutions?

My little boy learned to do this at same age and we just used a rolled up muslin cloth at his side to stop him rolling over but it didn’t take long before he learned rolling back so wouldn’t worry to much .

Thank you for your reply, I've used a rolled up towel to make sure she doesn't roll right over to her left. I was having major worries in my already sleep deprived state
