T.A.
We actually just bought a peter potty! My son has been potty trained since 22 months (we used the e-book three-day potty training method and it worked great). I like the PP because he likes to pee standing up, and got used to it because the potty at day care is little - it is kind of a pain with the whole flushing mechanism, but it is simple and I think anything that gets them to "want" to potty train can't hurt! It took him a little longer to poop regularly on the toilet, he was peeing on the toilet for a couple months before he was actually potty trained. I would recommend a "cold turkey" method at this point... maybe keep him in diapers and don't talk about it for a couple weeks, then make a big production of throwing out the diapers/pull-ups and getting big boy underwear (maybe his favorite character) and tell him it is time to be a big boy. We also had the little toilet in the bathroom since he was about one year old. Good luck!!
