Brumfield, 32, was found guilty in May of aggravated manslaughter, but she was acquitted of the first-degree murder and aggravated child-abuse, charges she originally faced, reports CBS affiliate WKMG.

Brumfield claimed the child, Olivia Madison Garcia, was trying to climb out of a playpen when the toddler lost her balance, fell about 2 feet and hit her head. She said Olivia was fine, and she even fed her a banana, which is why she waited two hours to call for help, reports the station.

At trial, Orange County Medical Examiner Dr. Jane Garavaglia testified that the death of Olivia was intentional, stating that it is impossible for a fall from that height to cause the three-and-a-half inch fracture and bleeding and swelling found in the girl's brain. But, the defense suggested the fall may have aggravated a previous injury, causing the 1-year-old's death.
