SISSY+MARLEY, a New York City-based boutique baby planner and concierge service, is a dream-come-true for trying-to-do-it-all new moms. A family team of two sisters, Chelsea and Rachel, and their mother, Diana, "gearing up for summer at SISSY+MARLEY means shopping for the three kiddos." Just like they do for their clients, these ladies listen to what their children like and want, all under the guide of their exquisite eye. "Ryan Marley, 3 1/2, has developed quite an opinion about what she'll be wearing. Only dresses and rompers will do, she is a total girl! Logan, 2, is preppy as could be, except on the days when he begs to wear a costume out of the house. Thankfully, Sebastian, almost 2, is still easy on us and is happy as long as he is comfortable and casual. One thing they all can agree on is their love for Salt Water Sandals. And, we couldn't be happier about that." SHOP SISSY+MARLEY'S PICKS >
