Stomach sleeping

Anyone having their little ones sleep on their stomach yet in the crib? My LO has rolled 2x from tummy to back but not sure if it was an accident or not!

She’s been a horrible napper and startles herself awake (transitioning out of the swaddle) so I thought I’d try her tummy. I’m watching closely on the monitor and checking on her very frequently. So far, Its been a 1.5 hour nap, but woke up 2x crying. She passes out right when I pick her up and I rock her back to sleep and put her back on tummy....

Would you keep trying sleep on her tummy? Not sure if I’m ready for night sleep like that yet though....thoughts?
