Michigan couple Teri and Jay Schwandt has a family of 12 children -- all of them boys. But they figured that trend would have stopped at child No. 12 and were looking forward to having a girl.

Except that didn’t happen. Instead, the Rockford, Mich., couple welcomed a boy, Tucker Ray Schwandt, to their family Sunday. The family of 12 now has enough children to form a full baseball team -- and three relief pitchers -- or three golf foursomes, as pointed out by Matt Lauer of the “Today” show.

Teri, 38, has spent a good part of the last 22 years as an expectant mother.

“Having another baby in the house -- it’s just natural now,” she told "Today." “We assumed that if we had anymore it was going to be just boys. We thought if we’re going to have a girl, No. 12 would be the one.”

Teri refused to say whether she was disappointed that Tucker was the 12th boy in her family.

“We are confident that he’s going to fit right in, and we gave up a long time ago on a little girl showing up in this family,” she said.

Tucker was born at Mercy Health St. Mary’s Hospital in Grand Rapids, Mich. He weighed 7 pounds and 12 ounces.

“Tucker -- he’s doing great. He’s acclimating well,” Teri Schwandt said.

Her husband, Jay, 39 chimed in, “This is a pretty testosterone-filled house.”

The Michigan couple didn’t plan on having 12 kids when they were married at 18, but Teri has the experience of growing up with a large family (she’s one of 13 children). Jay has only one sibling -- a sister. They left the size of their family up to the almighty.

“It’s up to God,” Teri told the Grand Rapids Press. “We figure God knows what he’s doing.”
