A nice bath with lavender to wash her body and feet. Dim the room, get off the phone, read her a book, and she won't be laying on the floor looking at you puckering up your beige lips taking selfies you don't post. There's too much light in the room and it's hot. She could be laying on the floor because it's cool.
Do they sell ceiling fans in England? I'm just wondering we live in the South and we run ours all the time even in the winter ( you can switch them making the hot air push down )They are cheap here and I couldn't live without mine.
