HOUSTON (February 19, 2013)—Defying long odds, Tressa Montalvo delivered two sets of identical twin sons on Valentine's Day at The Woman's Hospital of Texas, which says the odds of giving such a birth naturally are one in 70 million.
Montalvo, 36, delivered sons Ace and Blaine at 8:51 a.m.
Ace weighed 3 pounds, 10 ounces, and Blaine weighed in at 3 pounds, 15 ounces.
Cash and Dylan arrived a minute later, Cash at 2 pounds, 15 ounces, and Dylan at 3 pounds, 6 ounces.
Montalvo says she and her husband, Manuel, 43, planned the pregnancy but didn't use fertility drugs.
"I guess we just succeeded a little too much,” she said.
