In 2014, Alison O'Reilly broke a story about a mother and children's home in Tuam, Ireland, which had stored the remains of 796 children, in a septic tank. 

The home had been operational from 1925 to 1961, and was part of a wider policy to 're-home' children born to unmarried mothers, who were considered by the state to be unable to care for their children.

The story was reported on around the world. 

Six years later, on July 27th, another report involving more than 1,000 children who had died, this time at Sean Ross Abbey, was published. 

Alison talks to the Voice of the Child about the growing number of children who died in these homes, and how she came to break the story about the Tuam baby deaths.

We also discuss whether the mass deaths could be classified as genocide, as more information emerges about how the children died.

She also outlines what she thinks of the UK's care system today, why adoption and foster care policies need to change, and why she feels the voice of the child is still not at the forefront of social work.
