We've run him through the gamut of tests and all they have managed to figure out is what he doesn't have... So no autism, no emotionally disturbed, still haven't ruled out childhood bipolar.

I would try that, but I have no idea when he goes. He's not regular at all. Part of that might be due to the Miralax, so we're trying probiotics and cutting down on the Miralax to see if that helps at all. Th diaper would definitely make the potty less cold...
