Kateri and Jay Schwandy now have 12 boys, after Kateri gave birth to a boy on August 4.
The family lives in Rockford, Michigan.
They were hoping for a girl. They didn’t find out the baby’s gender ahead of time, so it was a surprise.
Kateri said that the family uses flow charts and other tools to manage the big family. When she needs help, the oldest son Ty, 21 year old, is there to help.
“I know how to manage time and manage a schedule and make sure kids get where they need to be and get picked up when Mom forgets every now and then,” he told local broadcaster WNCT.
Jay says the couple isn’t opposed to having more kids, though the couple hopes that if they do have a 13th it will be a girl.
