Woman Gives Birth to Rare Double Twin Baby Boys


Call it a miracle or simply a plain old rare event. Tressa Motalvo, 36, gave birth to two sets of twin boys on Valentine’s Day. The odds of delivering two sets of naturally occurring twins are one in 70 million.

Tressa and her husband Manuel are ecstatic about the new additions to their family.

“We planned the pregnancy – I guess we just succeeded a little too much,” joked Tressa.

The couple wanted to give their two-year-old son Memphis a brother or a sister. It was a shock when doctors discovered the third and fourth heartbeats when Tressa was 10 weeks along. The parents have since recovered from the news and the babies are doing just fine.

Tressa and Manuel decided to name the boys by the first four letters of the alphabet: Ace was born at 3 pounds 10 ounces, Blaine at 3 pounds 15 ounces, Cash at 2 pounds 15 ounces and Dylan at 3 pounds 6 ounces.


Multiple births often occur because of fertility treatments, but the Montalvos conceived without fertility help. The two sets of twins were the result of two eggs being fertilized; each set of boys shared one placenta. The boys were delivered safely through Caesarean section at The Woman’s Hospital of Texas in Houston.

Tressa says even though her pregnancy was unexpected, she and her husband feel blessed to have their boys. Manuel is still gunning for more children: he wants a little girl.

Congrats to the happy family.
