Wow I have already heard some great tips.
My favorite thing to do and I have done it twice so I know it works!!
The night before I BOMB his side of the bed full of good chocolate, candies, CD's, concert tickets, toys etc.
Things that are fairly flat. So when he goes to pull back the covers for the night he is pleasantly shocked.
(Then you grab all the dove chocolate and eat yourself silly!) What I mean you can then go from there!
Okay that is about as creative as I get. I hope to hear more great ideas from this gang!
