Zachary J. Robinett is reportedly charged with first-degree child abuse after the baby suffered numerous bruises to head and body, a skull fracture and bleeding in the brain.
He was reportedly ruled competent to stand trial Tuesday in Genesee District Court.
Court records reportedly show that an intention to assert an insanity defense has also been filed in the case.
The baby was reportedly found unresponsive after police were called to a home on Chicory Lane near Meadowcroft Drive on Feb. 11 in Burton. The baby was taken to a local hospital.
Genesee County Prosecutor David Leyton said previously that Robinett was left alone with the baby after the child's mother went to work. It appears to be a case of shaken baby syndrome, the prosecutor added.
"Doctors are referring to him as a miracle baby," said Leyton. "At first, they weren't sure he was even going to live."
Robinett is reportedly scheduled to be back in court June 12 for a preliminary exam.
