“We’re feeling both excited and exhausted at the same time. We’re looking forward to having a family. Now that he’s here we excited to grow our family a little bit more and spread our love even more," they told People in a statement.

Maddie married Caleb in June and they announced their pregnancy in November.

“We are both really excited and anxious,” Maddie told People at the time. “I think every soon-to-be parent is anxious, but we have so much support from both sides of our family.”

Her parents, Kody and Janelle Brown, are also over the moon about their new addition.

“I think being grandparents hasn’t sunk in yet. It’s so fun. I can’t believe how much we love this baby already,” they told the publication. “The whole family is excited. In fact, the biggest trick will be giving Maddie her rest because there’s going to be this long line of parents and siblings that will be continuously wanting to hold the baby.”

Maddie kept her fans involved in her pregnancy experience by sharing baby bump updates across her social media accounts. Last week, after she attended her brother Logan's graduation — it was clear that their bundle of joy would be arriving VERY soon.

She and Caleb opened up in the past about their decision to participate in a monogamous marriage, unlike the controversial ways of her father.

"We are not living plural marriage. We support Maddie's family with their choice of living plural marriage and they support us with our choice in just marrying each other," said Caleb.

Congratulations to the growing family!
