A 2-year-old child in its stroller was blown by the strong wind into Lake Michigan and he was declared Saturday to be in critical condition, after remaining for at least 15 minutes in the cold water.

The child’s grandfather, who was pushing the stroller around the lake Friday afternoon, did his best trying to save the little boy, the Chicago Fire Department said.

Witnesses reported that the 65-year-old man jumped on the harbor and struggled in the water, crying desperately: “Child!” “Child!” while continuously pointing to the dark water.

The little boy was still strapped into his stroller and the lower half of his body was in the water for a long time.

"The lower half of his body was in the water,'' said witness John Derscheid, according to Chicago Sun-Times. “I ran over there and he was looking around in the water. He had his head dunked in the water. . . . I said 'there's a ladder down here.' "

Divers from the Chicago Fire Department rescued the boy from the 40-degree water in about 15 minutes. His grandfather was also pulled to safety by the harbor master.

The toddler, who was unconscious after the rescue, was hospitalized at the Children’s Memorial Hospital Friday afternoon, while the grandfather was taken to St. Joseph’s Hospital, in serious condition.

Derscheid declared he had been strongly impressed by the viewed scene, saying that the image of the desperate grandfather trying to save his grandson would remain with him for the rest of his life.
