One thing that has really helped us in switching less is asking each other to teach each other how to do the things they are good at ourselves.
For instance, I (Emma) am horrible at resolving conflict or standing up to authority figures. Ivy is very good at this. In the past, if I was in a conflict with an authority figures, Ivy would take over. So, I finally asked her to tell me how she does it. I learned from her. Now I don't always switch in the same situation, I can try to handle it myself. So now we all try to learn from each other, and it's led to much less unplanned switching. We hope that helps!
