Katia Gutierrez was released from St. Luke's Hospital to continue her recovery at home.
Gutierrez was walking with 4-year-old Ariel Russo at the intersection of 97th Street and Amsterdam Avenue on June 4 when they were struck by an out-of-control car driven by an unlicensed teenager.
Russo died at the scene, and her family is suing New York City for $40 million over a four-minute delay in dispatching an ambulance.
The 17-year old driver, Franklin Reyes, is charged with vehicular manslaughter. He had only a learner's permit when he attempted to flee police pulling him over for reckless driving.
