Pollution-preventing parents are opting more and more for all-natural, organic children over their coal-burning robot counterparts. Green your growing girls and boys with today's Groupon: for $15, you get $30 worth of eco-friendly apparel for infants, toddlers, and children from K.D.'s Treehouse on Devine Street. This deal excludes local artists' consignment merchandise.

K.D.'s Treehouse, formed by Kris Burns and Dea Baughman in 2008, stocks eco-chic children's apparel, marvelously motley toys, plentiful puzzles and games, and green-conscious on-the-go gear. Smog-scorning styles from Kate Quinn Organics and K.D.’s Treehouse's own arboreal brand come in a customizable kaleidoscope of colors, like an excited chameleon on prom night. Amid the solar-powered swaddling for infants and children are multiple iterations of kiddie kimonos ($19), multi-dot footie jammies ($26), the floridly knit wildflower dress for ages 2-6 ($56), and a nap-nurturing sleepy hat ($16.99).

Art supplies such as planet-propitious molding dough ($24) and tree-free banana-fiber sketch pads ($12) inspire flowering fantasies while the puzzling Animal Memory game ($25) improves infantine intelligences. Finally the baby bibliothèque includes the nutriticational Today I Ate a Rainbow book-and-magnet play kit ($25), as well as world music for wee ones. Shipping is stork-delivered and free within the United States.
