3-4-4-3 custody schedule
Balance time in longer blocks
The 3-4-4-3 rotation alternates three- and four-night blocks so both parents receive seven overnights in each two-week cycle.

How the 3-4-4-3 rotation works
One parent has three nights, the other has four, then the sequence reverses. The pattern reduces transitions compared with 2-2-3 while keeping an equal two-week split.
Pros
- Balanced time in a two-week cycle.
- Fewer transitions than 2-2-3.
- Predictable three- and four-night blocks.
Watchouts
- Weekday responsibility can shift between weeks.
- Four-night gaps may not fit every child.
- Holiday exceptions need a shared source of truth.
