Texas Woman Welcomes Two Sets of Identical Twins

It’s a typical scenario—a couple has an only child they want to give a sibling to. But, deciding to add to their brood was the only typical part for Tressa and Manuel Montalvo of Houston, Texas.

At Tressa’s 10-week ultrasound the couple were jubilant to discover she was carrying twins. Then, more incredible news at the 12-week ultrasound—two sets of twins!

Tressa, 36, told Today “If I wasn’t already on the table lying down, I’m pretty sure I would have hit the floor.”

The odds of quadruplets being conceived spontaneously without the help of fertility treatments is one in 70 million, according to The Woman’s Hospital of Texas in Houston.

Dr. Brian Kirshon, a specialist in maternal and fetal medicine at Houston Perinatal Associates adds “And then if you take two sets of identical twins in the quadruplet set, the incidence must be one in many, many millions. It’s an extremely rare occurrence.”

At 31 weeks pregnant on Valentine’s Day, Tressa gave birth to four baby boys. Ace and Blaine were born at 8:51AM weighing in at 3 pounds, 10 ounces and 3 pounds, 15 ounces, respectively. Cash and Dylan followed one minute later, weighing 2 pounds, 15 ounces and 3 pounds, 6 ounces, respectively.

The quadruplets join big brother Memphis, two years old.

While Tressa was hoping for a baby girl to join the family, Manuel isn’t giving up. He told reporters he’d like to keep trying for a girl even with five boys.

Tressa isn’t convinced though saying, “For myself, I thought, ‘Okay, can we get through this first before I answer that?’”

We hear you! Congrats to the new family of seven.
