As co-anchor of the morning show Good Day LA, Jillian Barberie Reynolds is used to functioning on barely any sleep. And that skill is coming in particularly handy with her second child, newborn son Rocco. "I'm up every three hours," Jillian told Life & Style during an exclusive interview at her LA home on Jan. 27. "I don't care. I Twitter while I'm breast-feeding him. I call it breast-tweeting!"

Jillian wasn't quite as laid-back about Rocco's Jan. 11 arrival -- two weeks early -- via cesarean section. But she, husband Grant Reynolds (a stay-at-home dad) and their daughter, Ruby, 2, are happy just to go with the flow when it comes to their newest family member. "At my age, I was so lucky to get pregnant without help," Jillian says. "We didn't plan it. It was just natural."
