In moments of peril, superheroes don’t hesitate, they leap into action. And so, it seems, do little boys if their baby sister’s life depends on it. When 8-year-old Jaxson Dempsey realized his 20-month-old sister Lelia was choking on a chicken nugget, he didn’t panic. Instead, he calmly directed his dad to pull over the car they were driving in and proceeded to dislodge the obstruction from Lelia’s airway. Jaxson said he’d learned the lifesaving technique from watching WWE superstar John Cena perform the maneuver on an episode of the Nickelodeon show The Substitutes. Jaxson’s father Matt has nothing but gratitude for his son, whose quick thinking staved off a potential tragedy. “I couldn’t hear her because she was choking. She wasn’t coughing; she wasn’t panicking. She just had no air going through; she wasn’t breathing,” Dempsey told WNEP-News. “Thank God Jaxson was there because, without him, I don’t know if Lelia would be here.” While kudos were the last thing on Jaxon’s mind for doing what came naturally when his sister needed him, they’ve been rolling in nonetheless ever since.
