My husband and I never really sat down and discussed who was going to do what when we got married. For the most part we naturally fell into pretty traditional gender roles. He's always worked full time (or more), second shift for the most part, and I've always worked part time. So while he's has always helped out around the house and with the kids, I've done the bulk of the childcare, day-to day-housework (cooking, laundry, picking up, watering the garden etc.) and overall running of the house (organizing, planning, scheduling, filling out paperwork etc.) for most of our married life.

Every  once in a while we get into a small "discussion" over who has more responsibilities and how they should be divided (usually when I'm feeling particularly overwhelmed and/or annoyed that something he said he would do isn't getting done as quickly as I would like it to) but for the most part we just carry on doing the things the way we've always done them.
