the-little-couple-season-6-zoey-will-jen-arnold-bill-klein.jpg In a new episode of "The Little Couple," airing March 18, Jen Arnold gets a very serious diagnosis as she and her husband, Bill Klein, finalize the adoption of their daughter, Zoey. But while the cancer crisis is terrifying, the family still has some fun things in store for their new foursome.

Bill brings baby Zoey home to Houston for the first time with her big brother Will, where they join mom Jen and bond as a family. Since Christmas is around the corner, they begin some family traditions.

In Zap2it's exclusive clip of "Just Another Bump in the Road," watch Bill and Jen dress up the kids in their traditional garb for their holiday photo.

"The Little Couple" airs Tuesdays at 10 p.m. ET/PT on TLC.
