Trent and Amber Johnston and their five children make up the world's largest known family living with achondroplasia, the most common form of dwarfism, and star on the TLC show 7 Little Johnstons (Tuesdays at 10 p.m. ET). The point of the series, the two say, is to show that they are like any other American family. "I grew up in an all-little-people family," Trent tells PEOPLE. "[But] we didn't have a 'woe is me' attitude. My parents raised us just like every other parent would raise their child." Amber has a similar spirit of self-reliance: "I was the only little person in a family of average people, but my parents raised me the same as my siblings. Plus I'm the oldest, so even though I was smaller, I was always in charge!"
After welcoming children Jonah and Elizabeth, the Johnstons decided to adopt three more children from countries where babies with dwarfism are often abandoned — so along came Anna, Alex and Emma.
