"When Hayley died, we recognised that some of her care fell below our usual high standards and for this we offer a heartfelt apology for the distress that has been caused.
"We’ve taken all the steps possible to learn from this. We’ve gone beyond the recommendations of our investigation and improved the way we do things to ensure that no children or families experience anything like this again."
A coroner has begun summing up in the case of a one year old girl who died at Birmingham Children's Hospital in 2009.
The verdict into the death of one-year-old Hayley Fullerton is expected to be made today, more than three years after her death.
