The Philippine government has put forward a bill to provide free contraception to those who want it.
The authorities are keen to reduce the birth rate, one of the highest in Asia.
They are facing powerful opposition from the Catholic Church, which says that contraception is against the will of God.
But supporters of the bill say one only needs to go to a maternity ward like the one at Jose Fabella Hospital in Manila, to see just how urgently it is needed.
