We've tried just about with everything with DS. He recently turned 3 and we started about a year ago. We even tried sticker charts, and were *very* excited when he went to the potty two different times on the day we posted the chart. The first time he just went #1 and earned one sticker, the seond time #2 and he earned two stickers.
DH and I patted ourselves on the back. After many failed attemps at finding something that would work to get DS to use the potty, we knew we'd find someting that would work! That was easy! As a matter of fact it was too easy. We should have known better!
Once DS used the potty and received those initial stickers, he never used it again. Whenever we asked him if he used the potty, he would take us to his chart, point to it, and say "I already used the potty. I earned my stickers, see?"
Finally, very recently (a few weeks ago, in fact) we took down the chart. We stopped encourging him to use the potty, etc. Last week, we tried getting him to use the potty again. This time he pointed to where his chart used to hang and said, "Well, I already know how to use the potty. I don't need a silly sticker chart for that. I just don't *want* to use it." I asked him, "Why?" He let me know that it took too much time. If he went in his pants he didn't have to stop what he was doing and could get changed when he was ready (e.g. done with whatever he was doing) or uncomfortable.
*sigh*
