Karen Sosnoski's one-year-old son, Anton, was born with what's known as Mosaic Down Syndrome, a rare condition where some of his cells have the extra chromosome that causes Down syndrome and other cells don't. So as he grows, he could end up having all the health risks and challenges of Down syndrome...or just a few of them. Through a website, Karen found a kid with the same diagnosis, named Tim Colvin, who was doing really well...perhaps because his mother, Kristy, invented a surprising and unusual way to raise her son. When some people hear about what Kristy did, they're shocked. Karen went to talk to Kristy and Tim about how Tim was raised. (14 minutes) Children • Education • Mental Health
