Sleeping on her tummy

As I was getting water before coming to bed I had noticed that Tessa had rolled into her tummy in the crib. She has been doing this all week long but usually starts crying when it happens. This time she actually got comfortable and stayed asleep. Google says that if she can roll from front to back and hold her head up high then it’s ok if she sleeps on her tummy. She fell asleep after her 7:30 pm feeding which is why she is still in clothes. She woke up at 10:40 to eat so she is now wearing pjs to bed.
