What is the ruling regarding the 'Aqiqah for two daughters: is it with one sheep or a sheep for each?

The 'Aqiqah is a confirmed Sunnah on the seventh day for the capable guardian of the newborn. It consists of two sheep for a boy and one sheep for a girl, though one sheep is permissible for a boy. If a Muslim is blessed with two daughters, he should sacrifice one sheep for each of them, and one sheep is not sufficient for both.
