I know this will likely depend on different cultures. I am looking for that input.
Both my wife and I shower with our son - not all 3 a once, but one or the other accompanies him. Someone recently expressed the feeling (not a strong conviction) that it would be more appropriate for same sex showering to extend to this age and even beyond, but that Mother/Son showering didn't seem like a good idea after 5 or 6.
I had never even considered the notion that there might be something inappropriate in such co-showering. I recall my brother and I showering with my Dad until we were old enough to remember doing so - maybe 6 or 7. It never felt weird. But I have no recollections of bathing with my mother even though I know that I did so - so it must have stopped at an earlier age.
Am I in the minority? Should Mom/son co-showering be restricted/phased out sooner than Dad/son?
I don't believe this is a duplicate of When should parents stop changing clothes in front of children? because I am trying to learn more about whether the genders involved would affect the age at which it would be inappropriate to shower together. Also, showering has a proximity and physical component that changing clothes or simply being naked doesn't.
