Gardaí have issued a photograph of baby Maria who was found on the side of the road in Rathcoole in Dublin 12 days ago.
The picture has been issued in the hope of encouraging anyone with any information to come forward.
The baby was found wrapped in a fleece blanket in a paper Marks and Spencer bag on Steelstown Lane on May 8.
Gardaí say they have received a number of calls from the public since the original appeal was made.
Sergeant Maeve O’ Sullivan, Child Protection Unit, Clondalkin and Rita Byrne, Principal Social worker, Tusla.
They have been followed up but baby Maria's parents have not come forward.
Anyone with any information is asked to contact the Gardaí or the Child and Family Agency, Tusla.
They have also stressed that the baby's parents have nothing to fear.
