D.K.
If at all possible, change some of it BACK to the way it was and TRANSITION IT A LITTLE AT A TIME. Change or move this for one or two weeks, then something else. It will be a LOT easier for her to handle and adjust to.
I understand that some things won't work that way and that you may have to change two things at a time, etc. Is there a SPECIFIC reason you changed it? Or.....did you change it just to change it?
