The Tucson Weekly reports that the pair face two years in prison. Sentencing is set for October 3.

She was taken to hospital on May 15 after her eyes “were rolling into the back of her head” while she was being breast fed.

The couple refused to allow a blood test on the baby but eventually urine tests and a toxicology screening showed she had cocaine in her system.

Krystin Lisaius initially denied using cocaine but later admitted that she had snorted the drug while hosting a party on May 14.

On May 16 police found 1.59 grams of cocaine and a scale inside their home.

The pair currently have limited access to their child.
