Is it normal my mom would take us in with her to shower when we were toddlers?
I've noticed this habit in other families too, but I could see how some could find it "inappropriate". I think my mom just found it easier to bathe us at the same time she took a bath. This all stopped around the time we were five years old. It absolutely had *NOTHING* to do with sexual abuse and I am absolutely not claiming that against my mother. She was a good mom.
It just seems like an awkward habit some families partake in and some don't. I've even seen some dads shower with their young kids... I'm not sure how I feel about that (then again, how is it different?)
Anecdote: when my brother was 2 my mom turned to turn on the shower and he smacked her on the butt, proclaiming, "Is this fat?!" Bless you Jon, RIP 1988-2018.
