She told Newsday that she found a snake wrapped around her 7-month-old daughter's leg.
Abatemarco said she lifted her daughter and the snake fell off.
A relative removed the snake from the crib and placed it in a bucket until animal control officers arrived. A Long Island animal shelter is a temporary home for the snake.
A relative told Eyewitness News that the snake was close to four feet long.
The reptile has been identified as a California king, a non-venomous snake that's not indigenous to the region.
Abatemarco says her family doesn't keep snakes as pets.
Officials suspect the snake might have been inside the mattress or bedding purchased for the crib.
