Your crib and mattress can be one of the biggest investments you make for your baby. The crib is easy enough to clean with some nontoxic wood, or if you're a supermodern mama, acrylic, cleaner. Then tackle the mattress with a homemade cleaning solution of two parts water and one part vinegar with a large spoonful of laundry detergent. The detergent removes dirt and body oils, while the vinegar deodorizes and disinfects. Scrub the mattress with the solution, wipe it down with a damp cloth to remove residue, and then let it air dry. Then store both your crib and mattress in a cool, dry place, awaiting the arrival of number two!
