The baby girl found dead in Co Wicklow on Wednesday may have been born some weeks earlier than initially thought.
The remains of the baby were found at a recycling plant in Bray by a worker sorting refuse.
Post mortem results on the baby’s remains reveal she may have been born some weeks earlier than initially thought and that there is nothing to suggest any deliberate harm was done to her.
Gardaí also confirmed that the baby was a Caucasian female.
Detectives at Bray Garda Station are heading up this investigation and they have said that their priority now is the health and welfare of the mother.
They are appealed to her to seek medical attention and to contact them.
They added, if the baby’s mother or father were to contact them they would be treated “discreetly and sensitively”.
It is not known what part of the country the mother is from and gardaí also appealed to the woman’s family members who may have information to pass it on.
