You left your keys in the fridge, the milk in the car, and the baby at the supermarket. Clearly, assembling kiddie furniture that requires an architect’s degree is not in your stars. Stick to the basics. Way Basics, that is. The lightweight, recyclable self-build furniture requires no tools or brainpower: Simply peel tape, stick boards together, and voilà. (Yes, really.) Play it smart with stacks of colorful storage cubes in the tot’s room. Look out for new-and-improved playroom tables early next year. All pieces mix and match, so adding on is a cinch. In other words, as easy as 1-2-4. Available online at waybasics.com. SHOP Weego Baby What: Pimp your nursery with chic mini furnishings (Dwell Baby, Netto) at this bright new boutique.
