R.D.
I didn't push my son at all. I'd ask him periodically if him wanted to use the potty and he'd sit on the potty sometimes but never really showed interest (Though I was certainly ready for him to!!).
Then when he was 3 years and 2 mos old we were at his cousin's house and my son watched his cousin pee in the potty. Right then and there my son pulled his pants down and went for the first time (hallelujah!). Then I basically kept his bottom naked for the next few days and it was done. He pooped on day two and the following week he wore underwear to bed. It really happened fast with almost no accidents.
I've watched a few of my friends try the intense programs and they definitely had lots of regression and accidents. It seems like a lot of work. They started the processes well before me (same age kids) and my son was "potty trained" before them.
The other plus about waiting is that my son was able to go on the regular potty-no cleaning out kiddie potties :)
My daughter is now 2 yrs 2mos and I'm at that point where every time I order diapers I dreamily wonder, "Maybe this will be the last order...." But I see she's not ready-so I wait ;)
Good Luck!
