As for Maddie, 23, she was “surprised” about having a girl but “had no idea” either way up until the moment the couple learned the news.

“I went back and forth so much. I am way excited though,” she says, sharing that “Caleb’s family was really surprised and extremely excited” while hers “was a 50/50 split of people who guessed girl and people who guessed boy.”

“My mom was so excited and shocked, she got a little teared up. Something about a girl I guess,” Maddie adds.

As for the big-brother-to-be? “Axel doesn’t really understand yet, so we are sure he will just be happy to have someone to play with,” she tells PEOPLE.

The spouses of almost three years revealed their baby news exclusively to PEOPLE in January, when Maddie admitted that while “this pregnancy feels less real for some reason,” she’s “still over the moon” about their impending newest familial addition.

Axel, however, might “be a little jealous at first” considering his parents’ “world revolves around him right now and that’s changing just a touch.”

“He’ll have to share, which he’s good at, but I’m not sure about everything,” Maddie explained. “I think once he warms up he will be really happy to have another sibling.”
