These Illinois brothers share a lot more than just a last name.

Jose and Ivan Favela announced their engagements at the same time, had a joint wedding and, over the weekend, became fathers within hours of each other.

“He said, ‘You’re going to be an uncle.’ I was telling him, ‘You’re going to be an uncle, too!’” Jose told ABC News 7 Chicago.

Adding to the synergy: they both welcomed baby boys on Sunday — in rooms next to each other at Rush-Copley Medical Center in Aurora.

And while their other big life events were coordinated to be in tandem, their babies didn’t even have the same due date.

Both their wives said they were excited to share the milestones.

“I guess we just have to enjoy it,” Jose’s wife, Elvia Chaidez, said. “A big party all the time.”
