The newborn suffered broken ribs, bruises on his face and neck, and a laceration in his esophagus making it impossible for him to eat.
Police charged Casey Carlisle, 21, with first-degree felony abuse of a child resulting in great bodily harm and third-degree felony child abuse after they were alerted to the child's injuries by local emergency room officials.
"The injuries are indicative of abuse — physical abuse to the child," Farmington Police Detective Sgt. Robert Perez said in a phone interview. "Based on a statement by the mother, she was the only person that has had access to this child when those injuries could have occurred."
Hospital officials in Albuquerque also confirmed to detectives that the baby's injuries were consistent with abuse.
The laceration in the newborn's esophagus indicated "something was forced into his mouth and his throat," according to court records.
Doctors also noted four bruises on the baby's face believed to be caused by grabbing or holding the baby's chin, and two fractured ribs on the baby's back that were approximately 7-10 days old, according to court records.
A University of New Mexico Children's Hospital spokeswoman would not comment on the child's condition Wednesday.
Farmington detectives were alerted to the baby's condition by emergency room officials at San Juan Regional Medical Center after Carlisle brought the baby to be examined.
The baby was vomiting blood when he was first brought in, according to court records.
When local hospital officials confronted Carlisle about their belief the baby was abused, Carlisle's responses and "actions were not fitting for the situation at hand" and the mother appeared "elusive and unaffected by it all," according to court records.
Carlisle, who has two older daughters with her husband, Zachary, told police the family was at a barbecue and the baby began to cry when they left.
On the way to the hospital later that evening, Carlisle said the baby stopped breathing but after patting his back, he began to breathe again, according to court records.
Carlisle, during a conversation with the doctor in Albuquerque, said her daughter sometimes tries to sit on the baby.
The doctor, however, told police that the "broken ribs were consistent with force applied by squeezing and further stated it was a violent act," according to court records.
The Children, Youth and Families Department did not return a call for comment.
A preliminary hearing for Carlisle is expected within the next 10 days.
