EXCLUSIVE: Meet the Gardner Quadruplets, the Miracle Babies of TLC's 'Rattled'

ET visits the Gardner family quadruplets featured in TLC's new reality show following first-time parents.

ET visited the Gardner family quadruplets -- Indie, Esme, Scarlett and Evangeline -- who are featured on TLC's new reality show, Rattled, premiering on Tuesday.

"When people ask me, 'How do you do it?' I say, 'Well, you do it too,'" the foursome's mom, Ashley Gardner, told ET, "'but just repeat what you do with one baby three more times.'"

Rattled follows four groups of new parents as they experience a wide range of challenges, triumphs and milestones during the first year of their newborns' lives.

Ashley and her husband, Tyson, had already gone through several ups and downs before their babies' birth. After struggling through a long infertility battle, they were thrilled to find out that they were expecting four bundles of joy. What made the birth even more miraculous is that the babies are two sets of identical twins -- a 1 in 70 million chance!

But, amid the happiness, there was also an enormous amount of pain.

"I thought I was dying, I was so sick," Ashley recalled. "In my first trimester, I lost 20 pounds. I just looked like a skeleton. I was just so sick."

The delivery was fraught with potential trauma as well.

"There were 37 people total in the delivery room, so there were 17 for me, and 20 for the babies," Ashley revealed. "They were so tiny. My smallest was born at one pound, 13 ounces and my biggest was two pounds, 10 ounces, so they were very tiny, fighting for their lives."

After the delivery, Ashley and Tyson had to figure out how to support their family financially, which they are doing through their online business, A Miracle Unfolding. The couple uses their Internet shop to sell swaddling blankets as well as give hope to new parents.

"We had so many people buy a blanket for their future baby," Tyson said, fighting back tears. "They are going through the same struggle as we went through. The minute you hold your baby for the first time, you know everything is going to be OK. There is so much love there that there is nothing you wouldn't do for that child."

Rattled debuts Tuesday at 10 p.m. ET/PT on TLC.
