ROCKFORD, Mich. — A couple with 12 sons is expecting baby No. 13, and even though they’re sticking to their tradition of not finding out in advance whether they’re having a boy or girl, they said they’d be shocked if their streak is broken.

Jay and Kateri Schwandt’s baby is due May. Even though they expect it will be another boy, the couple said they would welcome either into the family.

“If we were to have a girl, I think we would go into shock,” Kateri Schwandt said. “It would probably be disbelief.”

If he had a choice, Jay Schwandt said he would love to have a girl, but they’re just “hoping for a healthy baby.” Still, he would like to see the effect of adding a girl to the mix in a household with 12 boys.

“I’ve experienced all the boy stuff,” he said. “As long as we are having all these children, it would be really neat to experience the other side.”
