Caleb has Trisomy 18. Jen spends a lot of each day checking her Facebook and hoping he's ok. In this video, you'll see he's pretty ok.
Oh, by the way, the Social Security Administration denied Caleb's parents for Social Security. Because the SSN doesn't understand what is needed to care for a Trisomy 18 baby - he's practically dead, don't you know - they denied the application.
