We started potty training my son over the Easter weekend this year, so very end of March. He turned 2 in January so was 26 months when we did it.
He got it quickly, by the third day he'd pretty much cracked it. After that he had the occasional accident if he was as busy playing but mostly made it to the potty every time.
His sister was born at the end of May and he regressed, started wetting himself constantly. Health visitor said it was to be expected, and just give it time so we just carried on and expected he'd get through the regression.
At first it got worse, he refused to go for a wee at all, wouldn't sit on the potty and even if he started wetting himself, wouldn't wee once we sat him on it, then would wee his pants again minutes later. Looked up some advice on withholding and did eventually manage to get him to sit on the potty using food colouring in the potty too encourage him to go.
After doing this for a few weeks we could get him to sit on the potty even without the food colouring. But he still won't ever say he needs a wee until it's already coming out, if we ask the answer is always no. But when we force him to go he sometimes does a huge wee, even when he's said he didn't need it.
We've been making him go every 90 minutes as we were worried he's stretched his bladder with the withholding and so maybe lost the feeling when he needed to go, but we've been doing that now for weeks and he still refuses to say when he wants to go.
Throughout all of this he's had no trouble at all with poos. He tells us when he wants to go and it's regular, not constipated etc.
He also goes fine in nursery. He was having accidents at nursery to begin with but they haven't sent home wet pants for at least two months now.
Any ideas what we do next? If he's done it in the past and he can do it in nursery he's clearly capable of it, I just don't know how to get him to have a wee without prompting him at home.
