I really like Sandra's response because a similar method worked for us. Before potty training I had a very "hands-off" approach in mind. We started around 2 and my son would sit on the potty with his clothes on but was terrified of it if we suggested taking off his diaper. So I decided he was not ready and we just waited a few months, letting him sit on it whenever he pleased. But after a while I felt like we were never going to progress, and as much as I would have liked to wait until his time was right, the preschool he started attending at 2 yrs 9 mo requires them to be potty trained by 3 yrs old, more or less.
I think they get so accustomed to going in their diapers without thinking about it that they need to experience "going commando" for a while in order to learn to pay attention to their bodies. The nice thing about this approach is that you are still pretty much letting them do it on their own. Some encouraging is not the same as bullying or controlling. You can calmly ask if they want to try to pee or poop, and remind them without being too pushy. For us, although their were set-backs, the first day that my son started running around with no diaper, he used the potty and continued to train himself after that. Anytime he got mad at me for asking or refused the potty, I would say ok. He also had a nasty fever one time and he was in diapers for a few days, and it was hard to get back into it after that but within a week, we were back on track.
He will be 3 on Jan 12, and he now only his a diaper at night (we co-sleep) and he'll even pee in a toilet when we are out with my help of course. I'm so proud of him! He still won't use the toilet-cover potty at home for some reason ... still has a floor potty. When he started preschool 2 days a week there were many accidents, so the next week I just brought his potty in. After 2 weeks of that he was fine to use the potty they have there.
Whatever you do, best of luck!
ps. Forgot to mention, the cookie-reward system worked well with him too! Especially when he was starting to poop in the potty, we had to up the anti a little because he was nervous about it.
