[step] You must lower the vault for safety reasons. You do not want the preschooler running at an apparatus that is at head height.

As a rule of thumb, the vault apparatus should not be higher than the middle of the chest. Ending2: [substeps] You can most easily move the equipment down, dropping it, while the child helps, and it can cause the skill to weaken. If the apparatus is touching the ground, throw your catch there. Ending3: There are ways to lower, so ask a parent to set up. [substeps] Pull the top one-third of the vault apparatus to one side so that it looks sort of flat on a fixed surface. Ending4: Place the vault apparatus horizontally in a safe place to minimize damage from falling. You should never leave a device out of reach of children in an arena or during a game.
