Unfortunately, only one day a week usually. Dh works 2nd and I work 3rd so one of us can always be with dd, so our schedules are such that it rarely happens. I do think it's important-we both grew up with family meals- just not possible for us right now. Of course, dd is only 1 now and still mostly breastfed, and we do have predictable time with all 3 of us together.
I do try on my nights off, but it never fails: if I spend all evening cooking he comes home and says he's not hungry, if I don't bother it's 'what's for dinner' the moment he walks in!
We do have Sunday dinners though. Us, my parents, his mom & g-parents, and whichever of his sibs that can make it get together every week without fail. I'm envious of those of you that can eaty together all the time!
