At 16 years old, Erin Compton was certain she would marry her now husband, Aaron. And at 19, a year after the two got married, she was certain they wanted to start their family. Having 13 kids though, that was never part of the plan. Now, 21 years later, the Comptons have a full house, ages ranging from 21 years to 10 months old. Ten of their kids are biological, and three are adopted. So, how do they do it? "People love to ask. And it's a teamwork thing," said Erin.
