(AP) -- A Cobb County judge has sentenced a 12-year-old Tampa, Fla. boy to two years of probation for the death of his 5-week-old cousin. 

Cobb County Juvenile Court Judge Gregory Poole last month found the boy not guilty of murder but convicted him of battery.  Poole sentenced him to probation and anger management classes on Wednesday. 

Brittiany Young said she left the children alone in the car July 4 while she shopped and returned to find her baby, Millan Young, limp and unresponsive.  Prosecutors said the boy shook his cousin and slammed her head against a hard surface.  The boy has been in juvenile detention since July. 

He was ordered to live with a relative in the Atlanta area but will be allowed to visit his mother in Tampa.
