1. Once the walker moves quickly, its inertia is large and it is difficult to control. In addition, some children like to swing their feet in the same direction and fly all over, which may cause strain on the roots and shoulders of thighs and sprained waist. In addition, some children can't wait for the walker to stop and jump in a hurry, which is also easy to cause falls and sprains. In this regard, parents should tell their children to keep their movements coordinated and not to move too much. Besides, they must stop the walker slowly.
2. Many children like to perform thrilling actions on the parallel bars, such as hanging gold hooks upside down, swinging, even eating, laughing and fighting. Some children are easier to get up than to get down, so they must not jump directly, which is the easiest way to trip. Parents should not only warn their children not to try dangerous actions, but also teach them some measures to protect themselves.
