In odd-numbered years, the parties trade. Other holidays alternate also.
Children spend a half day at each parent's home, with a hectic drive in the middle.
The disruption can be harmful to the children and frustrating to both parents. Mom and Dad agree that the children will spend every Thanksgiving with Mom. Dad spends every Christmas Eve and morning with the children. After the divorce, Dad remarries and wants the children to spend Thanksgiving with him and his new family. Mom also wants the children to wake up at her home on Christmas morning.
