This is new for my almost 6 month old. When we lay her down, she immediately rolls onto her stomach. That makes me nervous because she puts her face down instead of to the side. But also she keeps moving and pushing herself onto her hands and crying. I've tried moving her to her back but she immediately goes back to her stomach. I'd be fine with her sleeping on her stomach but she just cries. It's weird because when we do tummy time, she will not roll over either direction but all of a sudden at bed time she's a pro at rolling onto her belly, but not belly to back. Idk what to do.
