A Maple Shade toddler saved his grandmother's life Friday with a call to 911.

When Patricia Bolli started having a seizure, her 3-year-old grandson Jaden Bolli, the only other person in the house, applied his mother's recent lesson to dial 911 in an emergency.

The elder Bolli, 54, is in stable condition at Kennedy University Hospital-Cherry Hill, where doctors are working on a diagnosis.

"He's a very, very intelligent boy," Patricia Bolli said yesterday from her hospital room.

Bolli would have been alone that day, but she wound up babysitting Jaden when his other grandmother, who was scheduled to watch him, fell sick.

Bolli was taking out puzzles for her grandson, she said, when "I blacked out. I don't remember anything until I got to the emergency room."

Jaden's mother, Candace Robbins, said she had taught her son a couple of days before how to summon help, and she had him memorize her phone and license-plate numbers.

"It was probably five minutes, and four days later it's put into play," she said.

Jaden not only stayed on the phone with a 911 dispatcher but also unlocked the door for police.

"When I got the call at work, I was so proud of him, that he took in what I taught him," Robbins said.

She took him to Chuck E. Cheese's later in the day as a reward.

"He definitely doesn't realize that she probably wouldn't have made it if he wouldn't have called," said father John Bolli, of Philadelphia. "But he definitely knows he did good. I don't think he knows how good he did, or how important it was."
