Miss Chloe sounds a lot like my daughter. I always sort of knew where to look for missing things at my house. It was nearly inevitable that I would find things in my Erin's room. She had a thing for office supplies, and containers. If she was given a purse, she was always happy a happy camper. Erin would get mad at me for catching her doing things, or if I did something that she couldn't do yet. I can still remember how mad she got because I could play one song on the piano.
The best part is knowing that a child like this, really can be anything she wants to be as an adult. It can be a little scary and intimidating at times to know how smart your child is. lol I love your solution for slamming the door. I love when the consequences are directly related to the provocation. I often read about parents grounding kids, and I have never really understood it. When I was growing up there was nothing that we could be ground from. We were nearly always at home anyway, and we had to go to church no matter what. So I don't ever remember being grounded. We got disciplined other ways. Some of it was good and some bad.
I was even more careful about making sure that the punishment fit the crime with my kids. It must have worked, because both kids have been able to become self supporting, contributing members of society. They both moved out shortly after they turned 18, and have never needed to come home because they couldn't make it on their own. I am very proud of both of my kids.
