Mr. Palmeiro hired his mother to care for his children, all under age 18. His wife
                  was physically unable to care for them from 9/12/99 to 10/20/99. Although the period
                  involved is more than four weeks, it is not a four week period in the calendar quarter.
                  Therefore, because the wife's physical condition did not prevent her from taking care
                  of her children for four continuous weeks in a calendar quarter, the domestic service
                  performed by Mr. Palmeiro's mother is not covered employment.
