The orphanage was not large, housing approximately thirty children who were abandoned in the surrounding area, as well as babies born in the hospital but left unadopted.
Thanks to a partnership with nearby hospitals, children with no one to care for them were also brought to Rosa's care.
The orphanage was very clean, and each child was well looked after by the caregivers and by Rosa herself. Rosa's orphanage had the lowest rate of return by adopting families among many in London.
Almost every child was able to integrate well into their new family.
This was inseparable from Rosa's meticulous attention to the children. In many other orphanages, due to lax management, children who were adopted out often had psychological problems and could not fit into their new families. When adoptive parents could no longer bear the burden and could not tolerate it, the child might be returned.
