"Sister Wives" star Maddie Brown is having her first baby with her husband Caleb Brush.
The couple confirmed exclusively to People that they are expecting their firstborn in May next year.
"We are both really excited and anxious. I think every soon-to-be parent is anxious, but we have so much support from both sides of our family," said Maddie.
According to Maddie, they have yet to decide what the baby will call the four sister wives.
"We think it would be super cute to have different names for all the grandmas, like oma, grams or babicka," she said.
"Grandma said differently or in different languages. Ultimately they get to choose what they are called but my dad will probably be grandpa," she added.
Kody Brown, Maddie's father and the patriarch of the Brown family, has a total of 18 children from all his four wives, and Maddie's child will be his first grand baby.

Maddie also shared that she and Caleb have already decided on the kind of parents they want to be for their child.
"I think I'll be the disciplinarian parent just because Caleb already has such a soft spot for the baby. He already has so much love for the baby," Maddie said.
She also added that Caleb has no problem taking on the role of a loving father, and that she is going to serve as the pushover.
"Our child is going to have me wrapped around its finger," she said.
