Taemar McDonald, 22, remains in the Sandusky County jail on $250,000 bond.
Police arrested her Feb. 7, after she took her son, Xion, to the emergency room at Bellevue Hospital, according to a police report. Medical staff told Clyde police Chief Bruce Gower the boy had several skull fractures and bruising on his arms and his back.
McDonald told police she hit Xion a few days before seeking treatment, but she denied shaking him, the report said.
As medical staff prepared to take Xion to a Toledo hospital for treatment, McDonald told Gower she had "anger management problems," the report said.
"It is like I'm losing my mind," she told police, adding that she wanted her children away from her so she wouldn't harm them, the report said.
Her other son, 7 months old, was with his father in Fremont at the time.
McDonald told police she "mushed" her son, demonstrating a tap to the head with her palm.
Toledo doctors kept Xion at the hospital for about a week after they discovered at least one skull fracture, bruises and the lacerated liver, Clyde police Detective Brian Weaver said.
Sandusky County prosecutors authorized a felonious assault charge against McDonald the day she was arrested. Her case was bound over to a grand jury.
Jon Ickes is her court-appointed attorney.
While McDonald has no felony record as an adult, her juvenile records are substantial, authorities said. She previously lived in Green Springs, Fremont and Toledo.
According to Toledo Municipal Court records, she was convicted twice on misdemeanor crimes. In November 2010, she was part of a large crowd fighting outside a Toledo club when she threw a chair through a window and allegedly threatened police. She was convicted of rioting and criminal damaging.
A month later she fought with her brother outside a Toledo home. She was later convicted of disorderly conduct, although criminal damaging charges were dismissed. She had finished her probation in October 2012.
