The bereaved couple are still desperate for answers, determined to find out if their daughter’s life could have been saved while being treated at the county's biggest hospital.

The Grove House Infant School pupil died just two days after she was first rushed to the Norfolk and Norwich Hospital (N&N) with a mystery illness.

Initially, the youngster had exhibited cold symptoms, but her condition deteriorated and she began vomiting and falling unconscious.

Bonnie was first seen at the N&N on December 16, but staff decided she was well enough to be sent home.

However, she continued vomiting and was taken back to hospital on the morning of December 18.

She died just a few hours later, after her heart stopped and could not be restarted.
