“I never expected it. No fertility treatments. It was my first pregnancy, and at five weeks they did an ultrasound and I was carrying twins,” said Tamara Velazquez, who's been busy raising 6-year-old identical sisters Asley and Aslen.
“It's a lot of work. It requires a lot of patience,” Velazquez said. “They are very active and dominant, although each has a different character.”
Ten of the twin sets here are identical, and the other two fraternal. None of the mothers interviewed by The Associated Press said they had received fertility treatments, although most said multiple births run in their extended families including relatives living elsewhere. None of the families are related to each other.
