Around age 2, your child will start to have the strength and dexterity to jump up and down. This marks a major breakthrough in his large motor skill development, since jumping requires strong muscle tone in the legs, feet, and ankles, as well as good balance so he can land without falling. Once your child realizes he can do this, look out. He may start trying to launch himself from the couch or your bed. Instead of always warning him to be careful, let him practice his new skill safely. For example, have him jump off the bottom step of a staircase as you supervise. Trying out new skills as well as learning his limitations is an important part of your child's physical development. --Leslie Gross Klaff
