A recent trip to Live with Regis and Kelly brought back a flood of memories for Julianna Margulies. “The last time I was here he was 6-weeks-old,” she mused of son Kieran Lindsay, now 20 months. “It goes fast.”

Another baby seems even less likely given the long hours the 43-year-old actress is currently working on the new show The Good Wife. Sixteen hour days are the norm, she shares, often beginning at 5 a.m. and not ending until 9 p.m. The revelation prompted show co-host Regis Philbin to wonder whether “the little guy is saying at 6 o’clock at night, ‘Where’s my mommy?'” which prompted Julianna to quip, “Thanks, Regis. I feel much better now.”

All joking aside, Julianna says she is grateful for the flexibility afforded by her career. “I’m lucky, I get to take him to work most days with me,” she points out. “Even if it’s for a few hours.” She adds,

Kieran is the first child for Julianna and her husband of almost two years, Keith Lieberthal. The Good Wife airs Tuesdays at 10 p.m. on CBS.
