The pair celebrated their son with a woodland-themed shower, with Maddie donning a gray dress with a floral belt while Caleb opted for a flannel shirt and hat.
Maddie announced her pregnancy in November and is due in May.
“We are both really excited and anxious,” she 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.”
Maddie's father, Kody Brown, has 18 children with his four wives, one of whom is Maddie's biological mom, Janelle Brown.
While they might not be sharing their little one's name, Maddie and Caleb have thought about what their son will call his grandparents.
“We think it would be super cute to have different names for all the grandmas, like oma, grams or babicka,” Maddie said. “Grandma said differently or in different languages. Ultimately they get to choose what they are called but my dad [Kody] will probably be grandpa.”
The pair also talked about what kind of parents they'd like to be, with Maddie saying she might be the tougher of the two.
“I think I’ll be the disciplinarian parent just because Caleb already has such a soft spot for the baby,” she said. “He already has so much love for the baby.”
“I’m going to be the pushover,” Caleb admitted. “Our child is going to have me wrapped around its finger.”
