A New Jersey babysitter pleaded guilty on Thursday to shaking the 2-year-old girl she was taking care of to death, NJ.com reported.
The babysitter also admitted that she did not seek medical treatment for the girl, who was unresponsive, until hours later.
Instead the woman played games on Facebook, ABC News reported.
Sheila Polanski, 36, was first arrested in 2011 for the death of Madeline McHenry, who died on July 7 that year. Polanski, from Westville, was charged with aggravated manslaughter.
The babysitter violently shook the toddler and slammed her on the floor in the girl's home in Gloucester City, NJ.com reported.
Polanski confessed she shook the child because she was whining, ABC News reported in 2011.
"She threw her on the ground and then proceeded to go and play 'Yo-ville' on Facebook because there were Facebook entries of her playing 'Yo-ville' for the two hours while my baby lay there dying on the living room floor," Ted Helgren, McHenry's grandfather, told ABC News back in 2011.
When Polanski did call 911 it was too late. The child died two days later after she was taken to the hospital.
"I don't know what was going through her mind or how she could pick her up and shake her and throw her across the room and kill my little girl," McHenry's father, Dan McHenry, told ABC News.
Polanski, who came with references when she was hired, said she was stressed out because she was recently evicted from her apartment, ABC News reported.
Polanski faces up to 12 years in prison. She has to serve at least 85 percent of her sentence before she is eligible for parole, NJ.com reported. Sentencing is scheduled for May 2.
Little McHenry "had the best personality in the world, very outgoing," the child's father told ABC News. "She loved to sing. She's just the sweetest, cutest little peanut on the planet."
