My daughter and her boy cousin l, who lives in a different country so only see each other every 6 months or so, have always just been chucked in the bath together when we're on holidays since they were born (they were born 3 weeks apart)
I'd never had any Issue with this, but just en route to visit now and it popped in to my head that I'm not sure if they're now being too old to do it.
They're both just turned 5.
Nobody else seems to think twice about it and my daughter herself mentioned playing in the bath excitedly the other day so I'm probably worrying where there's no need.
Just wondering when others found it was no longer appropriate, I accept many probably thought it was never appropriate and didn't do it at all.
