Tragic St Helens youngster Violet-Grace Youens donated organs so other children could have "long and happy lives", her family has said.
The four-year-old died in hospital last night (Saturday) after her and her Nannie, Angela French, 55, were mown down in a hit and run incident.
Ms French remains a serious but stable condition, officers have said.
A Merseyside Police statement said Violet-Grace's pancreas and both kidneys were donated. And her family were: "Devastated by the loss of their beautiful daughter but they wanted the organ donations to benefit other children and give them a chance to lead long and happy lives”.
It added: "(Violet-Grace) leaves a 21-month-old brother, Oliver."
An investigation into the incident on Prescot Road on Friday (March 24) afternoon continues with detectives stating they are probing a number of lines of enquiry.
Two men were captured on CCTV fleeing the scene in the aftermath of the collision.
Officers are appealing for anyone with information that could assist with the investigation to contact Merseyside Police on 0151 777 6041 or the Crimestoppers line anonymously on 0800 555 111.
