We started PTing LO (2y2m) last week. He did great the first 4 days or so...maybe 1-2 accidents a day, but would sit on the potty for a "special treat". However, the last few days, he has REFUSED to sit on the potty maybe 90% of the times when we ask him (which I try to only do if he hasn't gone in an hour or so). The treats we were using are not working any more. And he is having more accidents--not like FULL pee accidents, but he will start to go in his undies, sometimes say something, sometimes not, and then pee more when we put him on the potty (which he is willing to sit on after he has an accident). He understands where pee and poop go.
So now I feel like my options are:
1) Stop using treats at all and just kind of go with it--don't make him sit on the potty and wait for him to tell me (I was okay with this when he was having very few accidents)
2) find a really special toy that he can only have when he sits on the potty (any suggestions??). My fear is that this will stop working, just as our "Special treat" reward stopped working.
3) table PTing until he is older (which I hate to do because I feel like we got a great start).

What do you all think? What would you do?
