Genuine question.
My son is 3.5 and up until recently, has refused to even consider the idea of using a potty or the loo. Last week he said he wanted to wear pants and so we put in him loose shorts over the weekend, and he did pretty well. Even was dry at night! He's pretty good at knowing when he needs a wee, but seems to struggle with knowing when he needs a poo. Overall though, it has been a success.
Back at preschool, where he is 5 days a week, and he has had a few accidents. Both days now, when we have gone to pick him up, they have put him back in a nappy. I can understand them not wanting to be cleaning up all the time, but I am not sure how else he is to learn. Is it unreasonable to expect them to support him with learning to use the loo, or should he be completely accident-free before we send him without a nappy?
