I own my own buisness. It is a gym and I keep two of my daughters, ages 1 and 4,with me. My 7 year old also joins me at 3:30pm after school. I do fine all day until the 7 year old arrives. She comes in like a whirlwind, asking question after question, climbing on every piece of equipment, and getting into things she knows is off limits.She doesn't listen to me at work, but is good at home. I realize she might want the attention, but she knows that this is my job and I have to work. She is only here for a couple of hours a day. This in turn gets the 4 year old wound up and it turns into disaster, making my job very hard. My question is what can I do to keep my 7 year to calm down and follow the rules. It has been a year and a half of this now and I am at my wits end.
