In the 2-2-3 residential schedule, the child lives with one parent for 2 days of the week, the next 2 days with the other parent, and then 3 days with the first parent. The next week it switches. Variations of the schedule include 2-3-2, and 3-2-2. The important thing about this type of custody schedule is that once the schedule is established, it is relatively easy for a child to get used to it. This is a form of shared custody and parallel parenting that benefits the child.
