It's tiny enough that it can still pass as a food baby, but Chelsea Houska's baby bump is certainly growing! The Teen Mom 2 star took to her Instagram Story on Tuesday, April 17, to share an update on her expanding belly, and at "almost 20 weeks," she's nearly halfway through her third pregnancy. Check out the video above to see Chelsea's adorable baby bump!

The 26-year-old announced that she was expecting her third child — her second with husband Cole DeBoer — in a sweet Instagram post back on March 15. "GUESS WHAT! A sweet baby girl will be joining the DeBoer clan in a few short months! We could not be more excited!" she wrote in her caption. Baby DeBoer will join big sister Aubree (8), and big brother Watson (1) sometime around early September.

Earlier in the month, the soon-to-be mama-of-three expressed her nervousness about labor, even though she's been through it twice already. She took to Twitter to get her followers' input in a poll. "If you went into labor naturally, were your second/third labors LONGER than your first or FASTER? My first was 4 hours, second was 1hr 20min." She added, "I'm scared this next baby is gonna fly right out."

Fellow Teen Mom 2 co-star Kailyn Lowry shared her three delivery times, and didn't provide much comfort to the worrying mom. "Mine were 13 hours, 16 hours, then 1.5 hours. Lol judging by your history, she might fly out." In a response to Kail, Chelsea further explained her fear of a quick delivery with her baby girl. "OMG I'm so scared that Cole's gonna be at work and I'm gonna go into labor at home with both kids here with me," she wrote back to the mom-of-three. "Gonna start prepping Aubree for labor duties!"
