Lipstick Jungle star Kim Raver didn't have to work out hard to get her figure back after giving birth to a Leo Kipling Boyer in October, PEOPLE reports

Kim Raver back in shape

"A little bit," her husband says , "but not like crazy."

"My big goal was to be able to nurse my baby," Raver, 40, said "I was lucky that it came off easily."

Her regimen: "Running after a 5-year-old and a baby," she says, referring to Leo's older brother, Luke. "Really, I've been eating really well, a full three meals and avocado. But I'm working 16 hour days, and I'm nursing."
