My ds has just truned 3 had totally regressed in the 'wee' department. We have no problem with poo's but he has been having more and more accident then today on collecting him from nursery he'd gone through all 3 sets of clothes. When I collected him his keyworker told me she had just changed his clothes and within minutes was soaked again. We were home within 10 minutes and again his was soaking. I just don't know what to do. If I ask he to go to loo he yells no and if I try and take him he has a tantrum. I've try to use a star chart but he says he doesn't like it. I just don't know what to do now. Should I put him back in pull-ups for a few weeks then start then training all over again?
