This rule changed pretty recently if I recall correctly. One of the CMs who is on this board has talked about it. She has said that they are able to provide limited help (i.e., finish pulling pants up), but it's definitely limited and minor. They're not going to let a child run around with their pants around their ankles, but they can't go in the bathroom and provide assistance the way Mom and Dad will. I think they said if your child is in pull ups, they ask you to come back every 30 mins to check on them. Also of note, a 3 year old can still use the nursery too, so if they aren't potty trained or you're not comfortable having them in a kids club, you still have an option
