The baby girl is safe and doing well, according to police who cared for her before turning her over to the custody of DCFS.
Investigators continue to try to track down the woman who abandoned the girl in their care Friday afternoon.
The child is described as Hispanic with black hair and brown eyes. She weighs approximately 17 lbs. and has both of her ears pierced.
The woman who left her at the Grand Crossing district station is believed to be between 18 and 24 years old. According to authorities, she went into the police station at 7th Street and Cottage Grove, mumbled something to the effect that she had forgotten something and would be right back. She never returned.
"After a few minutes, they realized the baby had been left behind. That's not a problem. We're glad she did that. She's a beautiful baby, and we've already had a ton of people calling to ask if it's possible to adopt. We don't deal in adoptions, but we would like to meet up with the mother and find out if she did this of her own will," said Lt. Laurel Bresnahan of the Chicago Police Department.
"The first thing we think about is, is the baby safe? Even though this is outside the parameters of the Safe Haven Law, we're thankful the parents tried to follow the spirit of the law, if not the letter, and that this baby is safe," the Save Abandoned Babies Foundation's Jessica Martinez said.
The Safe Haven Law says children 30 days old and younger can be left at hospitals, police or fire stations without fear of prosecution.
The infant girl is in a black and silver baby trend Expedition stroller. She was wearing a pink jacket with butterfly, covered by a Winnie the Pooh blanket.
Police say she was dressed for the cold weather and showed no signs of neglect.
Officers investigating the case are from the special victims unit and tell ABC7 Chicago they cannot be certain who the woman is and whether it was the parents'choice to leave the child behind.
Anyone who can help identify the child or the woman who left her at the police station is asked to call Chicago police.
