We've used a potty chart for DS since January. We never pushed PTing really hard so it took us until about June to fill it up (and this was including marking just sitting on the potty).

At some point along the journey I started giving him a reward when he completed each row. No big deal, since it took so long to fill up a row. Then as he started doing better we went to just filling it a circle when he actually went on the potty.

Now he's been in underwear for 2 weeks so my latest is he has to fill up a whole page (about 28 circles) before getting a reward (trying to wean him off). So how do I end the rewards? We've had a couple accidents and he still won't tell me when he needs to go (I tell him it's time to go and he does), so I think the incentive of a reward is still good for him right now, but obviously we need to cut the rewards off at some point. Suggestions?
