Hi, just wondered if anyone could help with this. We started toilet training on Monday and apart from one accidental wee in clothes the (weeing) experience has been positive. We haven't had a poo yet though and tomorrow morning I have to take DS (aged 3.5) to look round his new preschool. I'm worried he will have a poo-related accident while there but would it be a disaster for the progress we have made so far to put him in a nappy for the hour we are there? He is still in a nappy at night but has stayed dry during daytime naps. Any advice gratefully received.
