Baby rolling over in her sleep

Tirzah

My baby is a month old and she keeps rolling over in her sleep. I’ll lay her down on her back in her crib ( which is in our room ) check on her and then she’s on her stomach and flat on her face. I do t have anything in her crib, but I’m scared she going to suffocate. Is there anything I can do to stop her from doing this, I am getting zero sleep. I’m sorry if it’s a silly question, I’m a FTM so I’m not sure what to do.
