I take a 2-hour "lunch break" for housework, family, etc. After sitting still for most of the morning, the chance to move is actually welcome.
Then in the afternoon, I write fiction. I know a lot of people who set aside a certain amount of time for writing, but that's never worked for me (it always seems to involve a lot of staring at a blank screen...), so instead, I have a certain amount of words I write daily. Once those words are written, the rest of the day is mine for housework, gardening, personal enrichment, editorial duties (I work as a volunteer for an ezine...it's very cool, but also very labor intensive), or whatever. Of course, that's only my ideal schedule...when things come up or I have to be somewhere, things get shifted to fit in where they need to be. (I wish I could say that email and forums bite the dust, but unfortunately, my fiction is usually the one to suffer when something comes up. Must work on that...) Fortunately (
) that doesn't happen all that often. I have no life. 
but those years were difficult. Kudos to you (and WordGypsy who has 4 kiddos!) for balancing so much and making a success here at CC. It is not easy!
