North Yorkshire Police have urged the mother of the dead baby found in a wheelie bin in Richmond to see medical help.
Officers are still hunting for the woman after a member of the public found the corpse in a bin in a communal waste area at around 2.40pm on Monday at Whitcliffe Grange.
Paramedics attended the scene but the baby girl could not be revived and was pronounced dead.
Yesterday Ann Holt, head of midwifery at the hospital, said the mother risked medical complications.
"Our message is for mum to come forward for the serious medical complications that might occur following this kind of delivery, like bleeding and infection, but also from the point of view that we have a baby here without her mum, " she said.
"We would like to reunite the mum with her baby in our hospital."
Her words were today echoed by North Yorkshire Police, who told IBTimes UK their investigation was focused on encouraging the woman to seek medical help.
"Work is on going but the key is focusing on her [the mother] to come forward and contact medical professionals," a spokesman said.
"It's all about taking the steps to get her the help she needs."
Anyone who has any information that could help to identify the mother or has any other information that could assist the enquiry, please contact North Yorkshire Police on 101, select option 1, and pass the information to the Force Control Room. Please quote incident number NYP-01122014-0234.
