When Carlos and Erica Morales first found out they were expecting quadruplets, they were just excited to be pregnant. After Erica, 36, had a miscarriage, the couple went through fertility treatment and conceived their four little ones — three girls, one boy — through IVF, according to People.

But then, in a tragic twist of fate, heartbreak followed joy: Erica died after childbirth.  Despite his grief, Carlos told the magazine he remains steadfast for his children.

Carlos adjusts to his chaotic new life as a father to newborn quadruplets with the help of his family and America. Meet Carlos Jr., Erica, Paisley, and Tracy, who are all adorable.

“Nothing in my life had ever made me this happy,” Carlos Morales, 29, says. Yet a few hours after his four babies were born, everything went horribly wrong as the love of his life, his wife Erica, 36, went into hypovolemic shock and died after severe blood loss. “These babies don’t know yet what blessings they have given me. They have given me four reasons to live,” Carlos says.

“It was the best day of my life,” Carlos, 29, says. “Nothing in my life had ever made me this happy.”

But then, just a few hours later, that best day of his life turned into the worst.

After initially seeming fine, Erica, 36, went into hypovolemic shock, an emergency condition involving massive blood loss. She died at 1:20 a.m.

“These babies don’t know yet what blessings they have given me. They have given me four reasons to live,” he said.
