I don't get the impression that the original poster is looking for special treatment and more time off than other residents in the program because s/he is a parent but instead is looking for a program where there is some extra time for a life outside of work.
There's a big difference between a program where you are expected to lie about your 80 hour work week with very few golden weekends vs. a program where you actually do work 80 hours max (and average quite a bit less than that when you factor in lighter rotations) with 2-3 golden weekends per month.
There are family friendly ob/gyn programs - but it is hard to ask these questions during the interview days without coming across as a resident who doesn't want to work hard. I work my behind off when I am at work, but my life is more than just my job and I need just a little time for that as well so I get where the OP is coming from.
I found that the Freida database was pretty accurate in terms of call schedule, average hours per week worked, and what the residents told me on interviews. I obviously only have personal experience from my own program, but our hours and call are precisely what was advertised on Freida.
My program doesn't have a lot of parents but I consider it to be about as family-friendly as an OB/Gyn program can be. So don't use that as a deciding factor!
