A.J.
What is her age? It's normal for her to follow the crowd if she's in the 5-9 range. It's only a problem if she deifies your clear instructions in the moment when you tell her to stop. Like for instance when the farmer told them to wait. You need to explain to her she needs to follow the person in charge, not the group, and be firm enforcing consequences if she purposely chooses to break the rules. When you told her you were going to sit and wait for the instructor and not run around the church, did she? If so, no worries. Don't be alarmed at the fact she'll naturally have the urge to follow at this age. Sounds like she needs some explanation of what acceptable public behavior is even with no instructions (sounds like the other kids need it too), and you can work together on that. If she's older- like teens, this is more concerning.
