Couple With 12 Sons Awaits Birth of 13th Child: 'I'm Feeling Good'

— -- Kateri and Jay Schwandt were hoping their 12th child would be a girl, but weren’t surprised when they had another boy. Now, Kateri is pregnant with the couple’s 13th child. Will it be a girl?

“You know, people just assume that’s what we’re aiming for,” Kateri Schwandt said on “Good Morning America” today. “I just assumed we’d have another boy because we know what we’re doing.”

The family has traditionally kept the baby’s gender a surprise. It’s a rule enforced by Kateri Schwandt, her husband previously told ABC News.

“I try every time to have me find out and not tell her, but that never flies,” he said in October. “It’s not worth even asking anymore.”

“I’m very patient,” she added today.

The couple’s 13th child is due on Saturday-- and even with the birth expected so soon, Kateri Schwandt said she’s “feeling good.”

“My wife is pulling for another boy because that’s in her comfort zone,” Jay Schwandt, who does land surveying for commercial real estate properties near the family’s home in Rockford, Michigan, told ABC News last year. “I’m pulling for a girl.”

When their 12 sons-- Tyler, 22, Zach, 19, Drew, 18, Brandon, 16, Tommy, 13, Vinnie, 12, Calvin, 10, Gabe, 8, Wesley, 6, Charlie, 5, Luke, 3, and Tucker—were asked to raise their hands if they wanted another brother, only three of them did.

The Schwandts, who are both 40, manage their household of rough-and-tumble boys through a system of flow charts and chores.

“There’s a lot of activity, a lot of commotion, a lot of chaos, but there’s also a lot of love,” Kateri Schwandt said.

ABC News also talked to the family after the birth of their 12th son, Tucker Ray, who was born on Aug. 4, 2013.

One of the couple’s sons told ABC News then, “After like the seventh, it kind of became routine.”
