In 1984, the actress won over audiences as the colorful and rambunctious Punky Brewster. Now, the former TV cutie, 35, is a proud mom to daughters Poet, 6, and Jagger, 3. She's also part-owner of an eco-friendly L.A. kids store, Little Seed, and recently wrote her first book, Happy Chaos, which details her laid-back parenting style. "[I'm] constantly being reminded to just have fun," she revealed to PEOPLE. "To get on their level and to just be a kid myself."
