Can anybody recommend a good potty training program or book for a very stubborn boy? I'm trying to get my son into this daycare in town for the fall but they only accept potty trained children. :( He turns 3 this weekend and so far - throws a fit at being asked about the potty. He's never been in trouble before (as far as I know…) about potty or using diapers so I don't know where the potty hate comes from.

Right now he's full of apple juice and sitting on the potty with the iPad. I've got the stickers and M&Ms handy for when it happens...
