According to WPVI-TV, the births occurred at a hospital in Perth Amboy, Middlesex County. Baby No. 1, a boy, was born at 10:32 a.m. on July 26 to Pagliery Cabrera Nin. Baby No. 2, another boy, was born at 1:47 p.m. that same day, to cousin Jankelly Abreu and the newborn’s mother, Anais Garcia Perez. And last but not least, baby No. 3, a girl, was born to Keydy Cepeda, Pagliery Cabrera Nin’s sister, at 6:37 a.m. on July 27.

Cepeda recalled her labor starting shortly after learning her sister and cousin had given birth.

“They all gave birth, and then hours later, after I heard that they were giving birth, the pain started,” she told WPVI-TV.

The three didn’t know they’d give birth so close together. Cabrera Nin told the outlet that when they each found out about their pregnancies, they tried to keep it a secret.

“In November, she called me to tell me, ‘Oh I have news for you, I’m pregnant and don’t tell anyone,'” she explained, WPVI-TV reported. “And I said ‘I’m pregnant too,’ so it was in December that all the families were together, and then she said ‘I’m pregnant too.'”

The family’s rapid expansion must be a whirlwind for everyone, especially the infants’ grandmother. Garcia Perez, who birthed baby No. 2, told WPVI-TV that the children are three of many new babies in the family.

“His sister had a baby, his brother had a baby, we had a baby, she had a baby, and then his cousin had a baby, so there are six new grandkids for their grandma,” she said, according to WPVI-TV.

Cepeda, Nin and Garcia Perez were all set to return home from the hospital on Saturday.
