But the Cougar Town actress still managed to find a little time to express her appreciation for the kind words that have been coming her way.
"Thank you all for the warm wishes for our new little ladybug! It's been so sweet to read them all!!" Philipps tweeted on Tuesday.
Meanwhile, at the Los Angeles premiere of the new FX series, The Bridge, E! News caught up with Philipps' Cougar Town costar, Brian Van Holt, who couldn't contain his delight over the now mother-of-two's latest bundle of joy.
"Beautiful baby," he said. "I saw pictures."
Van Holt added that he had spoken to Philipps, but that she and husbnd Marc Silverstein have yet to decide on a name.
"I said Bobby," joked Van Holt, referring to his Cougar Town character. "I think they should name it Bobby, but they weren't going for it."
On July 2, Philipps gave birth to baby No. 2, who weighed 8 1/2 pounds.
"So this happened..." the 34-year-old actress tweeted the following day along with a pic of herself cradling the newborn.
The tiny tyke has an older sister, 4 1/2-year-old Birdie Leigh Philipps.
In March, Philipps told E! News that her second pregnancy hadn't been "so relaxing," and yet was "harder and easier" than her first at the same time.
Philipps also shared with the Huffington Post that daughter Birdie is "super-excited" about having a younger sibling, adding: "She's actually incredibly helpful."
