Hey there, friends! Let’s dive into the heartwarming world of the Gaines family. Joanna Gaines, the queen of home design and co-star of HGTV's Fixer Upper, recently announced that she and her husband, Chip Gaines, are expecting their fifth child. The couple made the delightful revelation on January 2nd with a playful Instagram post featuring their growing "party of seven." But here’s what makes this story even more special—Joanna isn’t the only one in her family adding to the baby count. Her younger sister, Mary Kay McCall, welcomed her sixth child just days later on January 4th! Can you believe it? It’s like a baby boom in the Gaines-McCall household!
Joanna's Sister Mary Kay: A Pro at Parenting
Now, if Joanna and Chip ever need parenting advice, they’ve got a built-in expert right in the family. Mary Kay, Joanna’s younger sister, already has five kids under her belt, making her a seasoned pro at managing a large brood. To top it off, she recently moved back to Waco, Texas, the Gaines family’s hometown, with her husband and their growing family. Their home renovation was even featured in a recent Fixer Upper episode. Joanna couldn’t contain her excitement when she shared an Instagram post back in September. She wrote, “Today’s house was my all-time favorite #FixerUpper. We got to reveal this house to my sweet sis and her family of seven (going on eight!). I can’t contain the excitement—after nine years, they’re finally coming back to Waco!” Talk about a full-circle moment.

The Gaines Sisters: A Bond That Inspires
Joanna and Mary Kay aren’t the only sisters in this tight-knit family. They also have an older sister named Teresa Criswell, who keeps things interesting with her YouTube show, Let’s Talk with Teresa Ann, and her blog, Triumphant Victorious Reminders, where she shares faith-based insights. The three sisters are incredibly close, and Joanna often shares Instagram photos featuring Teresa and Mary Kay, including plenty of nostalgic throwback pics. It’s clear they have a special bond that goes beyond bloodlines—it’s a sisterhood built on love, support, and mutual admiration.
Take Teresa’s heartfelt birthday message to Joanna, for example: “Jojo, you are a first-class peacemaker with a generous spirit, a heart of gold who has an ability to gather like I’ve never seen!” And Joanna returned the love when she celebrated the birth of Mary Kay’s fifth child, writing, “My sister shines, and I’m so proud of her!” It’s no wonder the Gaines family has become a symbol of strength and unity for so many of us.
