First, don't regress.

1. When you slide backwards, your head will land first, and the impact force will be borne by your head. Coupled with the violent impact with the ground, it is easy to scratch the scalp, but it will cause a concussion.

2. Children's bone tissue is soft and easy to deform under the action of external force. When children slide backwards, the cervical vertebrae will be severely squeezed, which may cause the vertebrae to deform and affect the growth and development. It is suggested that children can be shown a bone model.

Second, the way to teach children to play swings correctly

1. Keep the center of gravity stable and move back as far as possible. Because when the swing swings in the air, if the center is unstable, it may be in danger of being thrown out.

2. When sitting on the swing, grab the rope of the swing with both hands.

3. When watching other children play on the swing, learn to dodge and don't be hit by the swing.

When children are swinging, parents should pay close attention to their movements to prevent them from falling off their hands.

Third, outdoor activities safety precautions

1. Dress neatly before the activity, tie your pants and shoes to prevent wrestling.

2, understand the safety points, the correct use of mobile devices, understand what is the danger and preventive measures.

3, not crowded, potholes, damp and other venues for activities.

4. Don't push, pull and throw things at each other in the game, and don't hide in places that adults can't see at will.

5. Hold hands tightly when playing crawling activities and climbing, and don't push others.
