Highland Park residents Jenny and Dan Fairbanks weren't expecting their second child until January 4, when Jenny's cesarean section was scheduled.

"But he couldn't wait," Dan said.

At four in the morning on New Year's Day, Jenny's water broke.

"We were at home, and so I said, 'Get up! We're going to the hospital,'" Jenny explained on Sunday.

The couple drove to the Northwestern Lake Forest Hospital where, by chance, her obstetrician-gynecologist Dr. Tanner Colegrove was on call. Everything went smoothly, and Jackson Thomas was born at 6:32 a.m. The 19-inch-long baby boy weighed six pounds, six ounces.

His three-year-old sister Gabriella, who visited on Sunday, was eager to hold him.

"[To her,] his name's not Jackson," Jenny said about her daughter. "It's Baby Brother."

Both Jenny and Dan are Highland Park High School graduates. Dan, 38, is a third-shift custodian at Deerfield High School. He works on the side as a carpenter and recently received Heating, Ventilating and Air Conditioning (HVAC) certification.

Jenny, 35, is on maternity leave from her job as a school teacher at Montessori Connection. Both sets of grandparents live in the area and plan to help out when Jenny returns to work.

"For now," Jenny beamed, "I get to enjoy being home with them."
