The "5-2" pure joint physical custody may work like this: Overnights Mon./Tues with Parent A; Wed./Thurs. with Parent B; Alternating weekends including Fri./Sat./Sun. Each parent will have 5 day periods in alternating weeks which give a sense of stability/ home with each parent, without going too long without a either parent. It keeps the back-and-forth to a minimum. Children adjust to knowing for certain which day of the week belongs to which parent (i.e. a Tuesday field trip means Parent A, Friday spelling tests must be studied with Parent B, etc.) Pick up and drop off at school means less direct parent interaction in high-conflict cases. Each parent has time for employment and social obligations. Neither parent is the "visitor." Parents must live in reasonable proximity to one another to make this work.
