My son lives 50/50 with his mother and me. We trade off MT-WT-FSS (2 nights at one house, 2 at the other, then 3 at the first house). At the end of a year, we each have had him 50/50. Do we say he's lived with one of us 7 months, the other 5, majority falling to whoever is claiming him that year? Do we say he lived with each of us for 12 months?
