Stauffer previously revealed to fans that her baby boy’s arrival was imminent in a YouTube video that explained she was having steady contractions on and off.

In the clip, the then-mom-to-be struggled with contractions as the family went shopping at Target, and the couple predicted their son would be born on Father’s Day.

“I want him to come out. I hate being in limbo,” she said in the video, which was posted on June 17 — one day after the holiday. “I’ve noticed I’m a very impatient person.”

Stauffer also noted that she was more uncomfortable wrapping up this pregnancy than she was in any of her previous pregnancies.

The couple revealed exclusively to PEOPLE in February that they were expecting a baby boy.

“We were not 100 percent confident we wanted to find out,” Stauffer told PEOPLE at the time. “We were at an early ultrasound and the tech said she knew the gender right away. So [I had her] tell me and not my husband, so I could surprise him privately.”

She added that the reveal shocked her, as she was “positive” she was having a little girl and had already purchased accessories and clothes for a daughter.

“My oldest daughter was slightly upset at first. She really wanted a baby sister,” Stauffer said of Nakova, whom she calls Kova.

The couple had their son’s name chosen back in February, and teased that Axel, Alden, Rafferty and Bridger were at the top of their list.
