In Zap2it's exclusive sneak peek at the episode, Bill and Jen talk about how proud they are to celebrate their son's birthday with him. "It's a pretty big milestone for me to be able to celebrate his birthday. It just makes me very happy to be his dad. I couldn't be more proud," Bill says.

Jen is excited because it's the first birthday party they're able to plan for Will, and things get really adorable when they help Will spell out the "Happy Birthday" written on his balloon.

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