It also may help: Before you go into a public place, (like the library) you stop the entire group of kids right outside the door and let them know "what you expect inside" explain to all of them (with your stern voice and look ) that the library IS a quiet place, and they are all expected to follow the rules, listen, stay quiet and behave! I may also pick a "trouble child" and give them a "special task" while inside. " ________, I would really like you to help me find some super special books that me and you can read together later after nap." If this makes her excited...you also have some leverage while inside...."if you can't sit still, you will put your "special books" away!!
