I had a friend in primary school whose family did this - her Mum and Dad were always Sarah and Rick to their kids. My Mum used to hate it, she thought it was really affected. It really bothered her for some reason!
They weren’t especially hippy people, just quite relaxed middle class artsy parents (lots of music lessons and drama classes etc. in their house). I always quite liked the vibe of it and wondered if I would do the same with my own kids one day.
Anyway, got me wondering did any of you grow up doing this, or are any of you bringing up your children this way? Did you/do you find people are weird about it?
