The discovery of a grave containing the remains of as many as 800 babies at a former home for unmarried mothers in Ireland is yet another problem for the Irish Catholic Church. The mother and baby home at Tuam in County Galway was run by the nuns of the Sisters of Bon Secours and operated between 1925 and 1961. It took in thousands of women who had committed the mortal sin" of unwed pregnancy, delivered their babies and was charged with caring for them. But unsanitary conditions, poor food and a lack of medical care led to shockingly high rates of infant mortality. Babies' bodies were deposited in a former sewage tank. Sadly, the mass grave at Tuam is probably not unique. Tuam was only one of a dozen mother and baby homes in Ireland in the years after the Second World War, all of which treated their inmates in a similar fashion. During 10 years of research into the Catholic Church's treatment of "fallen women" - [a] book, Philomena: A Mother, Her Son, and a Fifty-Year Search, later turned into a feature film starring Dame Judi Dench - [revealed] that the girls were refused medical attention, including painkillers, during even the most difficult births; the nuns told them the pain was the penance they must pay for their sin. Philomena and thousands like her were forced to look after their babies for up to four years, bonding with them before they were taken away to be adopted. Many went to families in the United States in return for substantial "donations"; lack of proper vetting meant some were handed over to abusive parents.
