Concussional body-switching is such a common occurrence in anime worlds one would think the people are aware of it and that it has happened to Rosehip in particular many times before.

Does momhip know?

Judging by that look of utter confusion in panel 4, I doubt that she does know.

I don't think I've see anyone else quite so nonplussed throughout this series.

I love Shiho (Rosehip) face in the before last panel haha.
