Linn County Supervisor Brandy Meisheid was due Nov. 13, while her sister, Allison Sweeney, was due on Halloween. Doctors induced Meisheid early, and Sweeney's baby also arrived ahead of schedule. Cousins Myles and Kohen now share a birthday.

They are not the only new cousins. Sisters Taylor Campbell and Rachel Mantermach had their babies, Charles and Merritt, about four months ago, just three days apart. The four kids now go by the Quad Squad.

For this family, that means four cousins close enough in age to grow up like a set. "Having a family with four girls, it's always a lifelong dream to be pregnant together, but it was never anything we put pressure on ourselves to do," Meisheid said. She says the boys arrived in hospital rooms next to each other, and Myles and Merritt arrived in the exact same room. All four sisters and babies are healthy. "Everybody shares something in this story," Meisheid said. "There's just too much coincidence for it not to be a greater purpose or something."
