Yes!! I do not tolerate that aggressive behaviour. I would term on the spot. And if that was my daughter, mom would have been called right then and child gone!!!
I also do not take a child in that can not come in and follow our schedule. He must come in ready for nap if he's been dropped off at nap otherwise he doesn't come at that time. It's not fair to me and the kids who all just had a busy morning and looking forward to a quiet break afternoon.
