This, from the instructions from Form 2441:
For each month or part of a month your spouse was a student or was disabled, he or she is considered to have worked and earned income. His or her earned income for each month is considered to be at least $250 ($500 if more than one qualifying person was cared for in 2016). Enter that amount on line 5. If your spouse also worked during that month, use the higher of $250 (or $500) or his or her actual earned income for that month. For any month that your spouse wasn't a student or disabled, use your spouse's actual earned income if he or she worked during the month.
