If family lawyers learned anything in 2020, it is that custody and parenting time arrangements require great flexibility to endure and successfully protect children's best interests in the event of a public health emergency. We have learned important lessons—such as how to help parents pivot in the face of sudden and extreme changes in family schedules, how to create quality "virtual parenting time," and how to make up for missed time with children—and now we need to apply these lessons as standard operating procedure in 2021 and beyond.
