Childproof the garbage can with a piece of electrical tape
Jordan demonstrates that the simplest solution is often the best when it comes to babyproofing:
Our little munchkin, starting at about 9 or 10 months, began to scoot around furniture and the like, pulling herself up to a standing position. The garbage can posed too great a temptation, and soon she was digging around in old cans, pieces of paper and other miscellanea. A small piece of electrical tape works wonders; easy access for parents, and effective childproofing (so far - she's almost a year now).
