This story makes my blood BOIL!!! As a parent and grandparent, it truly upsets me to even share this story. I do so because there's nothing more important than the safety and well being of a defenseless child. Here's the story. Please be warned that the video is difficult to watch.

A nanny in Staten Island was caught by a hidden camera as she hit a baby while she was trying to feed her.

The mother of the 5-month-old girl had grown suspicious of the nanny that they had hired so she installed a video camera inside their carbon monoxide detector that was synched up to a live feed.

As the mother watched while she was at work, she saw Mamura Nasirova smack her young daughter in the face three times when she won't take the bottle.

Nasirova, 52, then shakes the girl as she lays in the stationary infant seat before whacking the girl on her legs.

No sound can be heard, but the motions of the child's mouth suggest that she is crying.

The Staten Island Advance identifies that child's parents as Mr and Mrs Roman Mardakhaev who live on Woodlawn Avenue, and the nanny has listed her address as the same as the family's. She is not a U.S. citizen and nothing else is known about the parents.

The Mrs Mardakhaev had grown suspicious of the nanny and was apparently watching the abuse in real-time, so she was able to rush home and yell at the woman at around 4.20pm on Monday January 28.

The parents filed a police report on February 1 and Nasirova was arrested two days later at the family's home.

Her fighting streak apparently didn't stop with children either as she reportedly fought with police as they tried to arrest her.

She now faces charges of endangering the welfare of a child and resisting arrest, and she is being held at Rikers Island, according to a spokesman for Staten Island District Attorney Daniel Donovan.

Her bail has been set at $1,000 but she remains in jail before her court date on Friday.
