PLAINVIEW - A Plainview nanny has been charged with assault and endangering the welfare of a 4-month-old child in her care, Nassau County police say.

According to investigators, Anneliese Brucato gave the infant Benadryl because she wanted to make her tired. They say the child's mother caught Brucato on a live video feed from a hidden camera inside her Laurel Hollow home.

Detectives say the liquid antihistamine is used to treat allergies in children over the age of 6 and that it can cause drowsiness and even seizures.

Brucato is currently being held on $30,000 bail.
