The Little Couple’s Bill Klein and Dr. Jennifer Arnold adopted a second child with dwarfism

Dr. Jennifer Arnold and Bill Klein of TLC’s The Little Couple adopted their first child Will from China earlier this year, and they’re already expanding their family!

The second addition to their loving home is 19-month old Zoey from India. “We’re so delighted that Zoey will be joining our family and that William will have a little sister coming home very soon,” they told People.

Both Will and Zoey have been diagnosed with dwarfism, something that’s important for Dr. Jennifer and Bill because of their own experiences. They feel that they have a purpose both as parents, and as reality stars to raise awareness to the public. “We’ve dealt with prejudice and many challenges,” says Arnold. “I feel very lucky and fortunate that I have the wonderful life I have.”
