A Dallas woman has admitted to subjecting her son to numerous unnecessary surgeries, medical treatments and hospital visits over the course of eight years, officials said.

Kaylene Bowen-Wright, 35, pleaded guilty to injury to a child causing serious bodily injury in relation to her son, who is now 10 years old.

Christopher Bowen was placed in his father's care after Bowen-Wright's arrest in late 2017.

Ryan Crawford, the child's father, had fought for years for custody of the boy but failed to convince family court judges that his son was healthy.

A Dallas County grand jury indicted Bowen-Wright in October 2015 after medical professionals who came in contact with the mother and son at hospitals noticed signs of medical child abuse.

During that period, Christopher went to hospitals and doctors 323 times, according to the Fort Worth Star-Telegram. He had 13 major surgeries, and the court documents say the unnecessary treatments began when Christopher was 11 days old and lasted until he was 8 years old.

At times, Bowen-Wright restricted her son to a wheelchair and unnecessarily kept him on oxygen.

On two occasions, the child developed life-threatening blood infections and required intensive care. He suffered serious injury from ongoing radiation, an arrest-warrant affidavit says, and had trouble eating and participating in normal activities because his mother convinced him he was sick.

In early 2018, child welfare workers told a judge that Christopher was thriving under his father's supervision.

Bowen-Wright's sentencing is set for Oct. 11. The agreement is an "open plea," meaning a judge will decide her punishment.
