Doing a maternity leave...this is NOT my normal age group...so somethings are BRAND new to me. Little girl went to the bathroom 3 times in the 2.25 hours we have. First time - she came out no problem. second time she was inthere so long. we wondered how we could have counted wrong with the milk and snack. Then she comes out when 95% have finished snack and gone on to free choice. (Do you GIVE her snack and milk at that point? - We did..but needing to move on, she was rushed to finish.) Lining up at the end of the day, she asks can she go to the bathroom... I hesitated, but that's ALL i need to hear that she had an accident on the way home...so i said yes. But she took about 10 minutes (she'd locked the door - so I couldn't open it to check. Need to get me a key!) and therefore we were all late getting to the door. This can't happen again. How would you, experienced teachers, handle this?
