Her uncle actually helped me put a codelock on the door and she immediately requested the code and it's been downhill ever since. I tried. Mostly I just wanted a space that I could leave things out that might otherwise be a little dangerous for my young child, but that ended rapidly. It's not her fault, I failed to properly and non-acrimoniously set a boundry. I should have perhaps bought a bigger house, but I imagine that would have just been filled with things as well.
