OMG She did it!

A went to sleep by herself for the first time ever. She has always needed someone to lay with her, rub her back, hold her, etc.....but tonight she asked me to leave (believe me I have tried this alot and it aways ended up with tears but this was the first time she asked me to leave.) I left, shut her door, turned on the monitor, and I heard nothing....20 mins later I went to check and sure enough sound asleep. WOW....and she is sill asleep. I have no idea what happened! But I am amazed! Yea A!
