Can't Sleep, Can't Figure Out What to Do

Tonight was the third night in a row that our four-year old has come down the stairs within five minutes of being put to bed. Each night is a new excuse: thirsty, help finding a toy to sleep with, etc. On the one hand, I don't blame him for having a hard time falling asleep. He is getting older and could probably stay up later. It also stays light later into the night. He is also so darn honest that I can't help feeling a little guilty for putting my foot down and requiring him to stay in bed once he is tucked in.
