According to the recommendations of the American Academy of Pediatrics, children should follow the following principles when doing stretching exercises:

Age limit: Stretching exercise is not recommended for children under 6 years old, because their bones and muscles are not fully developed, and excessive stretching may cause damage to their bodies.

Warm-up: Before stretching, children should do proper warm-up exercises to reduce the risk of sports injuries.

Step by step: children should take a step-by-step approach when stretching, and gradually increase the stretching range and time to avoid damage caused by excessive stretching. For details, please refer to Tallplus official website information.

Moderate: children should maintain moderate tensile strength during stretching exercise, and don't overstretch, so as not to cause muscle or ligament strain.

In short, children need to pay special attention to stretching exercises and follow the correct methods and principles in order to achieve good results and protect their health.
