It's small things that help. It is hard for her to be in the child position so I try to understand that and not make a big deal about it. And evening time, I go to my room and she goes to hers. The TV in her room helps.
I refuse to have TV in the common living spaces because then it's not only harder to clean, she keeps me up by watching it late. There were a few fights about that.
My mom is a messy. Which has been the hardest thing for me. I insist her mess goes with her.
