Prosecutors had sought to have the youth serve a three-year sentence at a juvenile facility, the maximum allowed under law.
The boy was originally charged with aggravated manslaughter in the Aug. 23 death of 11-month-old Tahir Francis of Carteret, who died from head injuries after being kicked at the Beverly Bryant Family Day Care facility in Woodbridge Township.
It is still not clear what provoked the attack.
Beverly Bryant, 64, who operated the licensed facility out of her home, was not in the room when the infant was kicked. Authorities have said Bryant was distracted by a phone call and other home chores.
The center was ordered closed and Bryant was charged with child endangerment. She has pleaded not guilty.
