i agree with Deb K. 2 yr olds can be weird about sleep. it is a phase. one of my boys (the easier one) would go back to bed (sometimes back to sleep) if i put on music for him. i could usually get another 30 minutes or more of sleep that way. the other boy couldn't sleep if he was the slightest bit hungry. so i started putting a cup of milk in the fridge and a box of crackers on the table the night before. that worked great for him and i often woke in the morning to find him in bed with a bunch of books and his cup of milk, totally happy. good luck!
