I started potty training DS about a month ago (when he was 3 and a bit, nearly 3.1).
We started on a Saturday and by the end of the Sunday he was doing well enough to brave pants for nursery on the Monday. That first week was a bit hit and miss, but not too bad.
Since then, generally he's been having (with the exception of 2 days we like to call The Regression) perhaps one accident every other day or maybe 2 accidents in every 3 days. So slightly more on average than one every other day.
Today he's had 2 poo accidents :( whch is quite a bad day for us.
But my question is this - how long should it take for the good days to become more and the bad days to be less often? I just wondered what others experience was and if it takes others this long to clear that last hurdle of 'the regular accident'? It's like he has the main principles but I just wish the accidents were less often.
I still don't think he should go back to nappies because he does 'get' what he's doing. Nursery agree that he's past nappies and we just need to suck it up and persevere. I think because of his age and the fact that he gets all bar, say, one right, we don't need to go back to nappies.
I just find it hard to understand that if he can do it most of the time, why can't he do it almost all of the time! I know it is difficult for them to learn, and I have to remind myself that it is just second nature to us as grown ups whereas he just gets distracted by something and I guess he's spent 3 years 'just letting it all go'.
Just need some cheering up I think please 
and the experience of others.
Oh, and since The Regression (which I can't talk about without therapy) we've been doing a sticker chart with a small reward for 5 stickers (I'm talking a few chocolate buttons or whatever). I did start off doing a reward every time he got through a day accident free, but if he had an accident early on then it was kind of game over for that day and nothing left to incentivise him. So we scrapped that and went with the stickers.
