In October 2008, Brumfield was babysitting her goddaughter, 1-year-old Olivia Madison Garcia, who died while in her care in central Florida.
Brumfield, 32, was initially charged with murder in the child's death, but was found not guilty.
"I miss Olivia just as much as anybody does," she said at Thursday's sentencing before breaking down, according to the Sentinel.
Since her arrest, Brumfield has maintained that the infant hit her head when she fell trying to climb out of a playpen.
Olivia's mother, Heather Murphy, told the newspaper that the sentence was "more than I expected."
Brumfield's best friend, Christina Stewart, read a letter from Brumfield at the sentencing, according to reports.
"Olivia brought joy to our family from the moment she was born," Brumfield wrote. "Olivia always was, is and will be my little girl."
