tummy time...and one nervous mommy!

Grayson's new found trick is that he loves to sleep in his crib...on his tummy! Much to my distress, he continues to do this every night! I have been a nervous wreck night after night about him in there like that. I have succumb to sleeping on his floor jumping up at every squeak making sure his isn't face plant into his mattress. I called the nurse today and she said that as long as he can move his head (he can) there is nothing I can do about his sleeping, if he is going to flip over, his going to flip over. Please pray that I can not be so anxious! At least he is sleeping MUCH better on his tummy!
