Kirra Max Bohan was born in the morning, weighing 8 lbs., 4 oz. Four days before her arrival, Patridge took to Twitter to reveal she was "getting nervous" about becoming a mom.

"Just waiting on the arrival of our little girl!!" she wrote. "Any day now."

While the reality star hasn't posted any pics of her little bundle of joy just yet, she wasn't shy about documenting her pregnancy journey via Instagram, sharing a slew of adorable pics of her growing belly.

"It's going to be weird not having a belly soon or feeling little kicks punches and hiccups allll the time," Patridge captioned one of the snaps. "I'm so used to it now and am loving it."

"I've had a pretty good pregnancy so I'm very thankful for that and also for good genes," she continued. "Just gotta get her to flip!!"

While most of her baby bump pics were selfies, she also posted a hilarious one of her 34-year-old husband-to-be sticking out his stomach in an effort to try and match hers. "2 buns and 1 in the oven," she wrote.

Patridge and Bohan, who are preparing to say "I do" in November, announced the exciting news that they were expecting last December.

"I finally figured out what to get Corey for Christmas! #babyontheway #ClearblueConfirmed #ad," Patridge captioned a photo of herself holding a pregnancy test. "Couldn't wait to share the news with you all! Xoxo."

She later took to her blog to share more details about how she discovered she was pregnant, also noting it was incredibly hard to keep the news a secret from her friends and family.

"I told everyone I was on a detox cleanse to cover my lack of alcohol consumption," she revealed at the time. "With the combination of my poor lying skills and Corey's perma-smile, we were given 'the look' over and over again by our friends and family, so it's safe to say the secret was not a secret much longer!"
