Elizabeth Escalona, 23, asked the judge who will determine her punishment to give her another chance.
"I'm asking for a second opportunity to show you I'm not the monster everybody thinks I am," she said. "I'm asking from the bottom of my heart to give me a second chance."
State District Judge Larry Mitchell could sentence Escalona to life in prison. Prosecutors are seeking a 45-year term, while Escalona's supporters are seeking to have her avoid jail time.
Escalona pleaded guilty in July to felony injury to a child for her September 2011 attack on Jocelyn Cedillo that the girl's siblings told police included hitting her with a belt and a shoe and dragging her around by her feet. Escalona also kicked the girl and hit her in the stomach with a jug of milk, authorities said.
Jocelyn has recovered from her nearly fatal injuries.
