Barb, my son is 2-1/2 and is very uninterested in potty training. My pediatrician said boys are later and usually training doesn't happen until they are closer to three. This is hard for me because my daughter was trained before age 2.
I think bladder control is key here, if they don't know how to control it - it is not going to work, and that might put a damper on the whole situation. We have sat on the potty and read books and he has pee-peed once, but I think it was not by his control (he was there an hour!). The next attempt he was completely disinterested, kept getting up, walking around, etc.
With my daughter, it took one day, she walked around with nothing on and pee-peed down her leg - she did not like that at all. From that point forward, she was potty trained. I may try that with my son in the spring, but I have heard that some kids just don't care. We'll see.
I have heard good and bad about pull-ups but someone told me that their kid treated it just like a diaper so it did not help. I haven't tried them so I don't know.
I think rewards (jelly beans, m&ms) are good IF the child has the control, if not, that could make them feel bad and have the reverse effects.
Try the potty seat and see what happens. I hope it works out for you. If it does, I will be tremendously envious and may have to fly out out to my house!
