Sleeping!

My little girl just turned 8 months old. She has always had a terrible time falling asleep. We have been using the Rock N Play for the past 7 or so months...but now it's time to get serious about transitioning to the crib once and for all! We have tried in the past but given up in the middle of the night when we're too tired to stay awake. She has basically completely out grown the thing and I know this is inevitable. Are there any tips out there besides the Cry It Out method which I will NOT do. Help is appreciated. 🙂🙂
