They say all good things are worth waiting (and fighting) for—and when it comes to being parents TLC's The Little Couple has had to do plenty of both!

Jen Arnold and Bill Klein's journey to parenthood over the past few years has been an emotional roller coaster, to say the least, and as they finally reach their destination, with the happy news of not one, but two, new additions to their family, TLC is taking a look back at their struggle in an hour long special—and OKMagazine.com has an exclusive clip.

"Full of twists and turns!" Dr. Jen adds.

After undergoing rigorous testing, Jen was given the heartbreaking advice not to get pregnant herself, due to her skeletal dysplasia

Cameras have followed the couple—who wed in 2008 and first appeared on TV in a May 2009 hour long special called Little People: Just Married—throughout the early days of their marriage, and their struggle to start a family has been well documented throughout the show's history.

As previously reported, after undergoing a series of rigorous tests, Jen, who is 3'2" and works as a pediatric doctor at the Texas Children's Hospital, was given the heartbreaking advice not to try to get pregnant herself, due to her skeletal dysplasia, a bone-growth disorder.

The couple immediately started looking into their best options and Jen subsequently had her eggs harvested and implanted into a surrogate.

The treatment worked pretty much straight away, but tragically, the surrogate lost the baby in the early stages of pregnancy.

Then the pair started the grueling process of adoption, enlisting the help of Rainbow Kids, an online agency that specializes in placing special needs children from overseas with families in the U.S.

And that's when the happy ending finally begins!

Bill and Jen were ecstatic when they learned they had been matched with Will, an adorable 3-year-old boy from China, who, like both his adopted parents, suffers from a form of dwarfism.

The excited new mom and dad flew to Asia to meet their son and have since brought him home to America.

Then, hot on the heels of their first adoption, Bill and Jen learned the happy news that they had also been matched with Zoey, a 19-month-old girl from India, who also has dwarfism.

Although Will is already a TV veteran, having made his small screen debut on the Katie Couric show where his proud parents introduced him to the world—we have yet to meet Zoey, but if she is even half as adorable as her big brother we're going to have our hearts stolen!

The proud parents! Finally Bill and Jen's dream is acheived with not one, but two children!
