Your toddler is all over the place isn’t he? Now he can run and climb and move astonishingly quickly, so even though you babyproofed when he was little, you’ll want to do it again now. Make sure bookcases and dressers are secured to the wall, since a climbing two-year-old can easily cause tall, heavy furniture to topple (yikes!). Sharp or dangerous objects such as knives should be secured well out of reach; two-year-olds are curious about everything, and they can reach more than you may realize!
