'Big Tiny' Premiere: World's Smallest Siblings Share Their Struggles And Triumphs (VIDEO)

The smallest siblings in the world are at the heart of TLC's latest reality series, "Big Tiny" (Mon., 10 p.m. ET). Brad and Bri Jordan are both in their early 20s and still living at home. But what sets them apart from other people is their stature. They hold the Guinness World Record for smallest siblings, and Bri has the additional honor of being the world's smallest living woman at 28 inches tall. Brad is almost a foot taller, standing at 38 inches.

The show shines a light on the normalcy of their lives, living at home with their mother and older sister, neither of whom have dwarfism. Brad and Bri are both primordial dwarves. At the same time, they have had to learn the limitations that their size puts on them.

One amusing sequence saw Bri out walking the dog alongside her sister Brandi. Only it looked to Brandi more like the dog was walking Bri.

Their mother said the family agreed to do the show because they "want people to know that anything is possible."

"Big Tiny" continues on Mondays at 10 p.m. ET on TLC.
