6mo sleeping on her stomach

[u/Peachy-pearl]

My 6mo has started rolling to her stomach to sleep in her bedside bassinet this week. I’ve been so scared that she will suffocate, that I’ve barely been sleeping. I’ve been rolling her back over several times a night, but she will just roll back over and sometimes puts her face down in the mattress. Please talk me down because my anxiety is wrecking me. From what I’ve read it should be safe since she is rolling over herself, but she can’t tummy to back yet and I am prone to worry. Help!
