So are their 3 days on a steady schedule (the same days of the week) most of the time, or do you schedule the 3 days in a more spontaneous manner?
I am considering a similar time splitting arrangement and am trying to understand how scheduling might work. I wouldn't want, for instance, to have one partner have all the weekend days and the other none. Scheduling the same set dates each week (with flexibility to change around as needed) would help set expectations nicely, but I also like the idea of scheduling the 3-day block about 2 weeks in advance based on what else is on the calendar. Does that seem workable, from your experience?
