Best For

Parents with unequal work schedules where one can handle more weekday caregiving but both want real involvement.

Pros & Cons

Pros

  • Gives secondary parent real weekday presence — school drop-offs, homework, dinners
  • Less demanding than 50/50 when one parent's schedule is tighter
  • Can qualify for shared-custody tax benefits in many states (check state rules)

Cons

  • Still unequal — secondary parent misses some key weekday moments
  • Exact day assignments vary by family; less standardized than 50/50 schedules
