Anyone else had to deal with this? He was fine at nursery, quite happy to go to the loo by himself, and has never had accidents at home. As soon as he was potty trained that was it. He has been at the school nursery since he was 3 and transfered to Reception in September but now has accidents at least once a week. It's hard to get a clear picture from him of exactly what is happening but it seems he holds on for too long and then doesn't make it to the loo in time (nursery loos were right next to the class but now he has to cross the school to get to them).
I really don't know how I can encourage him or help him to get over this, I've explained that he must go as soon as he feels the need, tell the teacher if it's in the middle of story time or whatever, there is no problem with leaving the class if children need to go.
Any advice appreciated!
