Seems this is a hot topic! I was actually quite frustrated as a parent, when my daycare provider required my son to wear a pull-up long after he was fully trained at home and was actually hesitant to help him train at all, thinking that he might be too young even though he was just over two. That is why I agreed to give it a try with this 20 month old. Her parents do not use treats and she does tell them when she needs to go. Today she had her first accident free day with me...yay! She does tell me when she needs to go, although I put her on a few extra times as well in case. I think it was just a matter of being confused because she had been going on the toilet for months at home, but wearing diapers to daycare, so she had to come to understand that she was no longer wearing diapers here. Her parents have provided cloth training pants, which we call underwear, to help with the mess in case. I can see already that she really is ready and is going to be fine soon, so I would be pretty frustrated as her parents if my daycare provider said she had to wait until she is 2 1/2 to train!
