Four-month-old Jourini Black suffered claw marks to the face when the raccoon attacked her while she slept then dragged her across the floor.
"She was laying on the floor - across the room - blood all over her face and her PJs," her mother told US media.
The girl has undergone surgery but could take a year for her to fully recover.
Her mother, Ashley Rodgers, says the attack happened late on Wednesday when she took her other child, a six-year-old boy, to the bathroom.
"We heard a sound upstairs and we see a raccoon run down the steps," she told CBS News.
