DS is 4 and a half, and is settled in school (as far as we can tell) but has in the last fortnight started reporting that he has wet himself at school, but didn't want to tell the teacher. And then proceeded to wet himself once or twice in the evenings, and this evening, three times. We are concerned that he is sitting in wet pants at school, and are surprised that when he has his accidents at home, he prolifically wets himself (rather than getting caught short, with damp pants and a hasty run to the toilet, as was previously the case when he had a very rare accident).
I took him to the gp last week, and no urine infection was detected, and we gave a further sample to be analysed at the lab, the results of which we await.
My question is, how do we help him? Is this behavioural? We have asked his teacher to keep an eye out but she said he is good at asking to go to the loo so was surprised, and hasn't noticed the accidents at school. I was half hoping it would be a UTI because then they can treat it, but I don't know what to do if it's emotionally related. He is a sociable boy, and seems happy on the whole (if a bit histrionic at times). When it happens we try not to react beyond saying "oh dear, never mind, better change your pants and trousers" but I am actually quite worried.
