It seems like just yesterday this "little peanut" was born, and now he's already walking!

Rachel Zoe and her husband Rodger Berman took their baby son Skyler for a playdate at a Malibu park over the weekend, and the little boy showed off his moves while his proud parents looked on. The celebrity stylist looked beach chic in a black maxi dress, green military blazer, and round sunnies, while her investment banker beau kept it casual in jeans and a flannel.

Skyler was definitely the best dressed for the occasion, and for good reason! The Rachel Zoe Project star recently revealed her mini-me was also her favorite client, since he has "no opinion" on the outfits she chooses for him, unlike some of her other diva clientele.

The happy family will soon be migrating East to spend the summer in the Hamptons, and we can only imagine the preppy outfits being put together to rock in the posh beach town!
