Children develop this symptom usually when they are 3-5 years old, and we recommend early detection and early treatment, which is best. The reason is that when it is detected early, the child has not yet become dependent on the habit of this behavior, as mentioned earlier, some children are not intervened in time, and when they reach the age of 6 or 7, they need to reach arousal before they can sleep, which really forms a habitual action. And he is not venting his bad feelings through this behavior, but slowly transitioning to masturbation. He has to reach orgasm and excitement after mucosal stimulation, and that is more difficult to treat than the boredom, fear, worry, and anxiety that comes with this behavior with small children. And the younger the child is, the easier it is for him to correct his behavior, because the younger the child is, the more influenced by the environment, so timely intervention and early help when the child is young, the best results.
