Wow, how frightening and I don't think I'd like that busy park at all! Now don't get mad at me beause I'm going to be honest. I only have a little teenager who comes to help me once in a while on her PD days, so not a real assistant. However, when she's here and helping me it is still my responsiblity to know exactly what is happening with every child. I'm liable for the children and responsible for everything that happens.
