you can get more hours if both members of the couple are unable to care for children for more hours - so if both work full time plus travel and simply cannot be there, or if they work late night shifts and put their children in FDC overnight, they can get more hours (so more than the 50 hour limit)

MD - i assume by the figure you're using, you must use FDC as it is different hourly rate to the LDC amount - where are you getting the 37.5 hours from? that may be related to FDC processing - at FAO, we only work with 24, 50 or more than 50
