"I picked him up and I tilted him downwards and gave him two or three back thrusts. He then was spitting everything up," Winters said.
The boy's mother, Nicole Hornback, told ABC News she tried to perform the Heimlich on her son, Clarke, 2, but was unsuccessful.
"I just was holding him out and running through the crowd trying to hand him off to anyone," Hornback said.
The mother hailed the cheerleader as "very brave".
Winters said she is thankful her mother taught her the Heimlich a few years ago.
The three reunited, but the toddler didn't remember Winters.
"It's hard for him because he's so young," she said. "He doesn't even remember what he ate for breakfast."
