You figured your kiddo had an earthy side when he suggested using the swimming pool for worm composting. Before jumping into dirty work, start an ecofriendly routine with Duck Duck Green. The website run by two moms/sisters-in-law sells natural, safe loot for newborns and toddlers. They’ve whittled the field down to their absolute faves for feeding, baths, play, clothing, and bedtime — all of it toxin free and fair trade. Finds like BabyGanics’s Germinator alcohol-free hand sanitizer and Natursutten natural rubber pacis don’t turn up at your local drugstore. Gift boxes, which gather all the category bests in recycled packaging, make it easy to give the most coveted present at the shower (the Bum Bums kit featuring nontoxic stuff for tushes is a big awwww waiting to happen). A portion of every sale goes to nonprofit 1% for the Planet, which supports environmental groups worldwide — a cause you’ll happily worm your way into. Available online at duckduckgreen.com.
