Matthews previously told PEOPLE that she and Terry shared the news of their growing family with their kids on Christmas.

Matthews also teased that baby No. 4 might not be the last time the family grows. “It’s so wild to me that we’ll be a family of six. I feel like it’s the Mormon in me coming out,” she said with a laugh.

“I’m surrounded by Mormon culture still, and my husband’s siblings all have so many kids. They’re like, ‘Once you hit three kids, you can have 10 kids.’ That’s kind of the mindset I have,” Matthews continued.

She added, “When people ask me how many kids I want, I’m like, ‘I’ve always wanted three or four, but I could see myself having six.’ “
