Police have issued an artist's impression of a newborn baby found dead in a laneway in Co Down five months ago.
They are hoping the picture will encourage her mother to come forward.
The infant, named Carrie by police, had been stabbed 11 times and had severe head injuries.
She will be buried on Thursday after an interdenominational service.
Police and Castlereagh District Council have joined together to ensure she has a proper funeral and grave.
The inscription on the headstone will read: "Baby Carrie. Known unto God."
Chief Supt Roy McComb said giving Carrie a decent burial was the right thing to do "morally, spiritually and ethically".
He believed the baby's mother wanted a funeral. The infant was found in a well-used lane which gave a strong indication that someone, probably her mother, was hoping the body would be quickly discovered.
"We want to treat Carrie with the dignity that she was not afforded due to the circumstances of her birth and death," he said.
Posters of Carrie will be placed around Carryduff.
They bear the message: "Carrie died in what must have been the most distressing circumstances for her mum and her family.
"We are worried that Carrie's mum may still be in great distress or even danger and in urgent need of support, care and protection, so please ring us.
"Carrie is all alone now and really needs someone to speak up for her.
"If you can be that person we will give you all the help that we can to deal with what has happened you and your family.
"All you have to do is pick up the phone."
