I recently had my Great Nieces and Nephew over for the week. Three children, age 4yrs, 10yrs and 11yrs. They stay often and they are generally good children. The older two do as they are told. However, the 4yr old can be very obsitinate and will not follow directions. She gets very pouty and wants to have her way. I've tried talking, giving her timeout and sometimes rewarding when she's done well. Nothing is working so far.

She ran out in the street on traffic, which of course scared me to death. She was scolded. Again, not listening. The next day she unbuckled her seat belt and reached up front and unbuckled my seat belt while I was driving. She was seated in the back when this happened. This simply was the last straw. I called her father and mother and explained this was just getting too out of control and thought it was best for them to come and pick her up. I was hoping this might teach her that when she misbehaves she will not be able to stay and enjoy the fun. She does love coming down to stay. I stated to my Nephew the other two children were welcome to stay and I would bring them back. They wanted to stay. Her father my Nephew stated to me I was overreacting and he would just take them all home. Did I overreact, am I wrong in this sitution? Great Niece, Nephew and the Children's Grandma think I'm wrong. My husband thinks I did what I needed to do. However, he warned that there's a price to pay. Because they may not want the children to come and stay anymore. I need some advise please. Thanks Nubia
