Lindsay Agbalokwu said she wasn't due until Sept. 17, so she thought a contraction she felt early Tuesday morning was a false alarm.

The teacher presented an award at an assembly before realizing she needed to get to a hospital. "Then all of a sudden, it was just so much pressure and pain, I was like, 'I think she's coming now! I think we need to just call 911,'" Agbalokwu told KDVR-TV. Marissa Kast, a seventh-grade reading teacher, put a sleeping bag down on the sidewalk in front of the school and principal Natalie Lewis and dean Chris Earls handled the delivery until firefighters arrived to finish the job. "I just like randomly think about it and text my mom, 'I just gave birth on the sidewalk outside my school!' This is so crazy!" Agbalokwu said. The baby, Zara, was born at 8 pounds, 6 ounces.

She's going to do great things."
