I know once babies can roll and hold their heads there is less worry about them sleeping on their tummy.
My 7 month old dd can't roll from front to back yet but she can roll onto her tummy and can hold her head up. I just found her rolled onto her tummy with her hands tucked under her and her face down into the mattress. I'd have thought she would turn her head to the side if she were going to sleep on her tummy. My husband thinks I'm being silly because I panicked and said she is going to suffocate.
Now I keep checking the monitor like a crazy mum and can't get to sleep. Should I worry or is this nothing to worry about?
