— -- Jay Schwandt and his wife, Kateri, have 12 sons and he was hoping their 13th child would be a girl. He didn’t get his wish.

Kateri Schwandt, 40, gave birth to another baby boy today, several days after her due date.

The baby weighed about 9 pounds and was 22 inches long, and after the birth his mother told ABC News that she was feeling “pretty good.”

They’re now deciding on names, with Jay Schwandt saying the baby's brothers would need to agree on the selection.

Even though Jay Schwandt had said he wanted a girl, he told ABC News that "being a dad, having 12 boys, one more boy is pretty cool."

The couple from Rockford, Michigan, has observed the tradition of keeping their children’s gender a surprise.
