It’s the little things! Teen Mom 2’s Chelsea Houska, who’s pregnant and expecting her first child with fiancé Cole DeBoer, took to Twitter on Thursday, July 28, to share her excitement over seeing her unborn baby develop.

“You guys! We got to see our cute little hunny yesterday ... we even saw the tiny little hand,” the reality star, 24, wrote, presumably after getting a sonogram. “my heeeeeartttt.”

Houska — who welcomed daughter Aubree, 6, with ex Adam Lind in September 2009 — has used social media to keep fans updated about her latest bundle of joy. On Monday, July 18, the South Dakota native expressed her joy in listening to her child’s heartbeat for the first time.

“I was able to find baby's heartbeat with the Doppler for the first time today,” the MTV personality tweeted. “I cannot handle it! I want to listen all day!”

Though she’s excited about becoming a mom of two, the 16 & Pregnant alum is a bit anxious about expanding her family. “I feel more nervous for some reason!” she tweeted last month. “It’s been a while and I want to do everything perfect. #deboerbaby.”

As previously reported, Houska announced her baby news via Instagram and her brand-new personal website on July 12.

“Oh my gosh! I’m so excited to finally be launching my website, and I felt like the perfect first post … would be to announce to everyone that baby DeBoer is expected in February 2017!” she shared at the time. “We are beyond excited for this journey and can’t wait to share it with you all! Big sister Aubree is also extremely excited, and it’s no secret that she is hoping for a girl haha.”

Houska met DeBoer at a gas station in 2014 and the pair got engaged in November 2015 after nearly a year of dating. They plan to tie the knot this fall. However, Houska's father, Randy, revealed during a June appearance on the podcast Dentists, Implants and Worms that his daughter’s nuptials will not be filmed for MTV.

“Chelsea’s getting married in October … she drew the line [on filming the wedding],” the dentist explained. “She won’t let them tape it. That was a lot of fighting back and forth. They certainly wanted it.”

“She doesn’t want it taped; she doesn’t want it on TV,” he added. “She doesn’t need it paid for. I was very proud that she grew the balls to say no. They’ll go to the bachelorette party and stuff [to film], but for the wedding she agreed that she’ll send a bunch of professional still photos [to them to use for the show].”
