I love these Sticker Activity Totes from Peaceable Kingdom, and would have loved to play with them when I was little (ok, maybe I still would!)

My trick is to leave about an hour before nap time, give him a sippy cup of milk, and put on his favorite CD (which has recently been narrowed down to his favorite song!). Then, I hold my breath, and if I'm lucky, he'll take a two hour nap. After he wakes up, I periodically pass him new toys to play with. These work great:
