Sharing baths with daughter

My daughter for many years hated baths and hair washing. But has grown out of that now. She bathes happily on her own I always stay in talking distance. My daughter has told me tonight that her daddy still wishes to share baths with her. I am worried, this does not seem right ?

How old is she and how does she feel about it? Was bath sharing how you got her used to bathing at all?

Best wishes,
Sadie
