A Pennsylvania woman who is addicted to painkillers is facing charges of allegedly killing her 11-week-old son with a lethal mix of drugs in her breast milk.

The boy died from a mixture of methadone, amphetamine and methamphetamine, the Bucks County District Attorney's Office said.

Jones told police she decided to breastfeed her son around 3 a.m. that morning after she was too tired to prepare a bottle, Philadelphia Inquirer reports.

A couple of hours later, she told police he turned pale and had bloody mucus coming out of his nose, the Associated Press reports.

Jones’ mother began CPR on the child after calling 911, court documents state. When police arrived, the child was in cardiac arrest and he later died at a nearby hospital.

Jones told police she had been primarily breastfeeding the child but switched to formula a few days before his death.

Jones told police she had been prescribed methadone because of an addiction to painkillers.

She told police she took methadone during her pregnancy and was taking it when the baby died.
