Since becoming a mother, "Girls Next Door" star Holly Madison says her partying days are long behind her.

"I am much more selective about the appearances I do because of the time it takes away from Rainbow," she told the fall issue of Mini magazine about her 18-month-old daughter. "I can't be this Tasmanian devil, whirling around to party after party every night anymore."

Hugh Hefner's ex welcomed her first child with now-husband Pasquale Rotella in March 2013.

Like other moms, Madison struggles with time management.

"Babies and toddlers simply demand all of your time. If I am alone with my daughter, I just have to accept that I am not going to get anything accomplished besides being a mom," the actor told the digital magazine.

At the same time, Madison, 34, said motherhood has "made me seek balance."

"I have to be very diligent about getting everything done during hours where I have some help with Rainbow," she said, adding, "I've been perusing more behind-the-scenes things too, things that will have a longer shelf life for me."

That includes writing a book.

"Right now, I'm working on a book and I love it," she told Mini. "I feel so productive without ever having to get out of my pajamas."
