Crawling in my Sleep???

This is how my mommy and daddy find me most mornings! I don't know how I do it, but I love to get into this position to sleep. Even though I am on my tummy, my doctor says not to worry. She said that if I can roll from side to side then if I put myself on my tummy then it is ok to leave me that way. I must be sleeping well...check out the drool stain next to my mouth :) Maybe I am so excited about crawling that I am doing it in my sleep?!?!
