Position we're in is that technically we started "training" ds2 in half term. He's got the point with wees, but (unless he's supposed to be going to bed and is delaying) he doesn't initiate going to the toilet himself so I have to remember the last time he went and make sure I take him in time. About every 1.5 hours seems to be the magic number at the moment, unless he's had squash (at toddler group or nursery) in which case I have to take him every hour.
Some days are fine, no accidents, other days I'm continually changing him and washing clothes. I know he can do it because it's extremely rare he has an accident at nursery and that's 3 hours long.
We haven't had a single poo on the potty or the toilet. All in pants or night-time nappy. I've got to the stage now where I really want to tell him he can choose to do it in his nappy or the toilet as long as he doesn't do it in his pants - not sure if that will help or hinder though! This part is the bit that is really getting me down to be honest.
On the other hand, he's doing better in one respect than his brother at a similar age - he'll use a real toilet when we're out. With ds1 I was dragging a potty around with me for months. Makes life so much easier not having to.
So anyway, I think my real big goal is to get him to not poo in his pants. I can cope with the having to time to get to the loo for a while. It's dealing with poo encrusted pants my patience is wearing thin with...
