PROSPER, TX — In a quiet neighborhood in Prosper, Texas sits a home that isn’t quiet like the others. Cue the babies crying!

Meet the Riggs Family. They have three sets of twins, welcoming the last set just three weeks ago.

“I didn’t think we would have six, by any means. That was for like, crazy people,” joked Mark Riggs, the father of six.

For five years, the Riggs tried to get pregnant the old-fashioned way.

“So we had to go through the fertility route,” said mommy Kristi Riggs.

After five more years, success! They welcomed their first set of twins Tatum and Lincoln.

“One day we’re like, I don’t think our family is complete yet,” Mrs. Riggs said.

And with that, another round of In Vitro and their second set of twins — Titan and Steal.

As for the third pregnancy, well, Slate and Maxon were a bit unexpected. They came the old-fashioned way.

“I was just in denial for a while until we finally saw the sonogram,” Mr. Riggs said. “I think I was not freaking out for her and she wasn’t freaking out for me, but I think we were both freaking out together.”

Freaking out for a good reason. It’s not easy keeping up with six kids, especially when the oldest are just 7 years  old.

So, what’s the secret to raising three set of twins?

“I don’t know if we should be giving advice to anybody,” Mrs. Riggs said while laughing. “I feel we’re just trying to make it day-by-day.”
