Who says you have to speak about work our children?
I speak about DS if I think its something others might be interested in (which isn't very much because lets face it do I really care if a friends child enjoyed their ice cream?), I never speak about work as its very confidential.
I often have discussions about things like music, books, movies and general topics that I have in common with my friends. Many of whom are parents. If they ask about children or advice then yes I will happily discuss for hours.
Anyway I'm being completely unobservant today as I've just noticed this is a femenist conversation which I don't normally take part in, so I shall bow out :o
