We are currently in the process of moving, going from a single story to a two story. In our old house, I currently have a rule that runs a goodnight routine at either a specific time, or if we go to bed early at the push of a button as we enter our bedroom. If my daughter is not home it will leave the hallway light on for her based on her presence. If she's home and still up, I will turn the hallway light back on since its easy for me to see if her light is on as I go to bed and in either scenario she manually turns off that one light when she goes to bed.
In the new house she will be downstairs and we will be upstairs and I am trying to figure out a way to handle the goodnight routine going forward. I am thinking of giving her a button in her room and using the pressing of each button to trigger actions specific to each area and then when both have been pressed running the full goodnight routine. I am really looking for ideas here if anyone is doing something similar. Also still trying to figure out how to handle the nights she stays at her moms.
