She rolls!

Khiana started rolling at 4.5 months, about 2 weeks ago. Since then, we've been constantly nervous that she will roll off the bed/sofa etc... understandably so, since she has succeeded in doing so several times. Now we keep a close watch on her and prop her up between pillows if we have to set her on the bed. When she first started rolling over, I was startled in the morning to find her peeking out at me over the edge of the crib. She now prefers to be on her tummy most of the time and even sleeps that way sometimes.
