Our 8 month old daughter starts off the night in her crib, and we bring her into our bed when she wakes up in the middle of the night. For awhile now, she's been flipping onto her tummy in her crib and sleeping that way. I've gotten over my fear of SIDS with tummy sleeping, since she's over 6 months and can flip herself back over. But over the last week or so, she has gotten into the habit of burying her face into the mattress while she sleeps. She no longer turns her head to one side - now she literally has her nose buried into the mattress. My husband and I have tried to gently turn her head to the side when we see her do this, and she always wakes up. And then she does it again the next time.
I'm worried about her breathing in her own carbon dioxide.
Has anyone else's baby done this? She never does this in bed with us, only in the crib. Any thoughts?
