A year after three newborns were brutally slashed by a berserk nanny at a Queens care center, two of the babies are with family back in China — and the third, who suffered two deep cuts to her face, is now lead plaintiff in a $10 million lawsuit against the center’s owners.

The baby, Chloe Cao, suffered nerve damage to her face and may be scarred for life, her family’s lawyer told The Post of the aftermath of the bloodshed at the Meibao Center in Flushing.

“They are rather big scars, really big,” lawyer Kenneth Jiang said after filing suit against Xuexin Lin and Meiying Gao in Queens Supreme Court.

“It’s terrible, at that tender age, to sustain that kind of injury,” he said of the 13-month-old’s injuries — a 2-inch slash under her nose, and a 4-inch slash on her chin.

The lawsuit claims that when Lin and Gao ran their unlicensed center in their illegally subdivided, three-story brick row house, they were negligent in hiring and failing to monitor overnight employee Yu Fen Wang.

The center, which also called itself the Mei Xin Care Center, turned into a horror scene when Wang allegedly attacked the cribs and two adults with a butcher knife and a meat cleaver early on Sept. 21, 2018.

The Meibao Center offered month-long care and lodging for newborns and their mothers, and was popular among recent Chinese immigrants and pregnant “birth tourists” who came to the US to deliver their babies and secure them coveted American birth certificates.

It is no longer in business, Jiang said; the owners could not immediately be reached Thursday.

Wang remains in Rikers, charged with multiple counts of attempted murder in the stabbing spree.

She has tried to kill herself several times in jail, her defense lawyer said a year ago.

The baby’s parents are hard-working, green-card-carrying citizens who cannot afford the multiple surgeries that Chloe will need as she grows up, the family’s lawyer said.

The baby spent much of the first months of her life crying in pain, he said.

Meanwhile, “the two other families, they all left and went back to China.”
