We use a spot in our hallway too, everywhere else, including the bedroom has far too much stimulation etc. I usually follow a time out with, thankyou for sitting there so quietly now we can go and play lego, do drawing, etc together. We also tried and do the distract/ redirect etc first though, and something my MCHN taught me was to always deal with the injured first, so if DD hurt DS when he was little, I would comfort him give him a cuddle etc while ignoring her, and then deal with her, she learnt very quickly this wasnt the way to get my attention.
