Bill Arnold and his wife, Dr. Jennifer Arnold, have adopted a little boy who was born with dwarfism, a condition that the Arnolds both live with and chronicle in their TLC reality show "The Little Couple." They had been attempting to have a biological child using a gestational surrogate, but their surrogate suffered a miscarriage in November 2011. More from PEOPLE.com on the Arnold's son, William, who is 3 years old and is from China:
"We are thrilled to announce that we have adopted a beautiful young boy from China," the couple said in a statement to PEOPLE. "We are so proud to welcome William to our family and look forward to bringing him home."
On their TV series last March, the couple explored adoption after their surrogate suffered a miscarriage.
"My entire life, even before I met Bill, I always thought, 'Oh, I'd love to adopt a child who is another little person,' " Arnold said on the episode. "And Bill and I talked about it after we got married, and I think we both realized we both would like that."
The new season of "The Little Couple" will premiere on April 30 at 10 p.m. EST.
