While it may seem like the greenest choice to reuse an antique crib or buy one secondhand, it can actually be a dangerous one. Because babies spend the majority of their time sleeping, it makes sense to invest in the very best, non-toxic crib you can find. Older cribs may have peeling paint, broken slats or could have been recalled. If you insist on reusing a crib that isn't too old, check www.recalls.gov to make sure it's safe. When buying a new crib, be sure to find one coated with nontoxic paint or finishes and made with sustainable materials like bamboo. Another green, money-saving tip: Look for convertible beds that easily transition from a crib to a toddler bed, extending their usefulness.
