Jeanine Sammis, 36, was caught on camera slapping a 1-year-old toddler on the back of her head on different occasions in late September, according to Nassau County police.
Police said a worker at the day care recorded Sammis after witnessing the alleged abuse.
Grace Pok's daughter attends KinderCare and she found the allegations upsetting. "I feel terrible for the baby's mom."
KinderCare issued a statement to WPIX and said, "We take all concerns about our teachers and staff seriously and follow a very specific protocol anytime a concern is raised."
