Nanny captured on camera sitting on yoga ball while 'violently bouncing' baby as his head snapped back and forth — and it wasn't the first time: Cops

A 29-year-old California nanny was captured on camera repeatedly hitting and violently shaking a baby for nearly a month before trying to work with another family after she was busted, authorities say.

Iara Dossantos Bomfim stands accused of 10 counts of felony child abuse, according to the Orange County District Attorney’s Office.

The baby’s mother discovered the alleged abuse when she heard the 3-month-old crying and went to check on him at their Irvine home. Bomfim insisted everything was OK.

But the nanny cam footage showed otherwise. Video from July 11 allegedly showed the defendant “sitting on a yoga ball and violently bouncing the baby as his head and neck bounced back and forth and side to side.”

Bomfim also punched the baby in the back of the head, prosecutors said.

The footage allegedly showed more.

A review of footage revealed Bomfim “violently punching, hitting, and shaking the baby” for nearly a month, authorities said.

She also allegedly allowed the boy to fall “headfirst” off the bed and in another instance was captured “forcefully” throwing the boy onto the bed.

Bomfim fled to her native Brazil after being confronted about her actions, prosecutors said. She allegedly tried to set up another online account advertising her nanny services, but the Irvine Police Department arrested her when she returned to California on Oct. 23.

She pleaded not guilty and is being held at the Orange County Jail on $500,000 bond. She faces 18 years in prison if convicted.

“This family’s nightmare began the moment a monster disguised as a loving nanny walked through their front door with open arms to care for their brand-new baby, and this should serve as a powerful reminder to parents everywhere that evil can hide behind the friendliest of smiles and the heartiest of laughs,” Orange County District Attorney Todd Spitzer said in a statement.

He continued: “Whether it is a nanny, a coach, a music teacher, a tutor, anyone who is around your child should be fully vetted and anything suspicious must be reported to law enforcement. Abuse lurks in the shadows, and it is up to all of us to shine a light on it and shield the voiceless and the defenseless from harm.”
