Just wondered if anyone had any experience of this. DS toilet trained quite late but picked it up very quickly. He will be fine for a few weeks, but then reverts back to this for a few weeks and will then be fine again. We have parents evening on Monday and it just happened at school for the first time (been happening at home for a few days).I'm really embarrassed! He refuses point blank to eat any fruit or veg so I'm not sure if he's constipated and this is contributing to the problem. Any advice?
