Jordan Zoey Licht was born 5½ weeks early at 10:59 p.m. on Dec. 31 at Cedars-Sinai Medical Center in L.A.
"We were planning to go to a New Year's Eve party when my wife started having contractions," says Licht, 38, who played Jason Bateman's brainy brother on the series. "I'm thrilled – shocked that it was this soon, but thrilled. Everybody's healthy, and it really was an incredible experience."
Jordan weighed 4 lbs., 10 oz. and was 18½ inches long. "She's already taller than me." quips Licht, who says he's enjoying feeding the baby and even changing her diapers. "My time is 4 a.m. on so my wife can get some sleep. I really love the time I have with her."
Licht and his wife Kimberly, 38, an actress who has appeared on episodes of CSI: NY and Charmed, married over Memorial Day weekend in 2007. It's the second marriage and first child for both.
"My wife is such a trooper," says Licht, who now runs his own financial planning company, JL Capital Management. "I'm a blessed man."
Licht announced the impending birth to PEOPLE in December 2008.
