During the incident, which took place last week, Trooper David Sabillon of Troop K, responded to a Dutchess County supermarket in the town of LaGrange for a report of an unresponsive child.
At the scene, Sabillon began life-saving measures and the 1-year-old regained consciousness and started breathing normally, state police said.
The child was taken to a local hospital and is in stable condition.
"A life saved, thanks to his quick thinking and training," Troop K officials said.
