DD will turn 5 months old on the 18th, and did her first back to belly roll this morning.
Well now she just refuses to stay on her back, her naps today she's rolled onto her belly and she's asleep now but on her front, I flip her on her back she goes right back on her front.
I'm terrified now of going to sleep incase her face gets buried in the mattress!
I have got a 4 year old DD too but I never remember worrying about this with her, but then she didn't roll till nearly 7 months so she was bigger.
