Problem with 6 year old?

As hard as it is, you are just going to have to deal with it. I am on the other end with my litttle brother but if you just put stuff that you dont want her getting into away and maybe lock your room and then go out somewhere with your best friend because that is what it is really about and maybe talk to your mom about going out with their parents and taking jess with them to like a zoo or something kid friendly.
