It happened at the Ribault Bay Village in the 1000 block of Bunker Hill Court in Mayport just off of Assissi Lane. According to police, 29-year-old Rickey Valentine was watching four children younger than five including an 11-month-old baby boy.
The boy is in life-threatening condition at Shands but doctors expect him to survive.
JOhn Harrell with the Florida Department of Children and Families is reminding everyone that with the new laws for reporting child abuse that have just gone into effect this week, it is mandatory for people to report abuse or neglect.
"It doesn't just have to be a parent. It could be a babysitter or someone else who, maybe caring for children, might hurt children...basically the laws have been strengthened. These are now some of the toughtest child abuse prevention laws in the country. We need people, if they see something, to say something."
Valentine has been taken into custody and charged with aggravated child abuse.
