TANF

A parent is incapacitated if a medically determined mental or physical impairment results in a substantial reduction in the ability to support or care for the child. This impairment kept or will keep the parent from performing the parent’s usual work for at least 30 days.

The individual's usual work is the individual's main occupation for the last 15 years. In the case of a homemaker, the activities related to caring for a child are considered usual work.
