First of all, children under 3 years old usually lack adequate motor control and physical coordination. Their hand-eye coordination and motor skills are not fully developed, so they may find it difficult to hit the ball or run effectively. In this case, it is inappropriate to put them in a regular competition venue, which may have a negative impact on their interest and self-confidence.
Secondly, children under the age of 3 usually don't have a deep understanding and mastery of the rules and techniques of sports. Soft tennis is different from traditional tennis in terms of rules and competition methods, but it still needs to be understood and mastered. For children under 3 years old, they may not have mastered the basic rules and techniques of sports, so participating in formal competitions may make them feel confused and depressed.
In addition, children under 3 years old are usually inattentive. It may be difficult for them to concentrate on the game. In this case, they may be more easily distracted or lose interest and cannot actively participate in the competition.
In short, children under 3 years old are not fully mature in physical and cognitive development, and their motor control ability, technical understanding and concentration are limited. Therefore, for their physical and mental health and positive participation experience, they are generally advised not to enter the regular soft tennis court for competition.
