Thanks Sarajo! If I put her to bed on her tummy in the middle of the bed, she goes out like a light. She doesn't tend to roll around unless she's either wide awake or I put her down on her back. Regardless, I put pillows down so that she can't roll over the side.

Regardless, it's the first time I've ever left her there on her own for a few minutes; as I'm usually in bed with her. *L* Thanks for the suggestion/reminder though!
