I find it very family friendly in that my hours are extremely flexible and I work when and how I want to a large extent, plus it's always acceptable to change plans for a childcare emergency.
Ways i don't find it family friendly are that in my field all the "successful" people are working very hard, long hours, travelling a lot. Many of them don't have children, though some do, but in the end it's hard to actually be successful in my area without putting in a lot of work which isn't always compatible with having children. Some people manage it.
I think that's partly why quite a few academic feminists are a bit anti children, they know very well just how much it affects everything else.
