Burrito Baby

When it comes to sleeping, Isla is just like her mama. She's a stomach sleeper who LOVES to have blankets near her face. When I put her in her crib, she sits up for the first few minutes, so I am never able to cover her up. She very quickly discovered how to wrap herself in the blankets, and it cracks me up (I watch her on the video monitor)! Anyway, she lays down, grabs a corner of the blanket, and rolls. Burrito style. This method gets her covered, but a lot of time her whole head is wrapped up tighter than a turban. She falls asleep (or maybe passes out) quickly when she is so cozy, but I always have to run in there and rip the blanket off of her head! I'm starting to get nervous about her suffocating herself! Last night, Andy didn't notice that she had fallen asleep with the blanket around her head. I went in there to take the blanket off and she was drenched in sweat. I'm not sure how to solve this problem because she absolutely won't sleep without blankets anymore (and I don't blame her!). Thoughts? Suggestions?!
