Medication: Choice of drugs such as chlorpromazine, oxybutynin, desmopressin, and so on. 2. Psychological support: Eliminate children’s nervousness, do not scold or blame, arrange reasonable living habits, and reduce drinking water before going to sleep. 3. Behavioral therapy: according to the time of urine loss, prolong the time of waking up the child; when there is no urine loss, give rewards; when there is urine loss, ask the child to wash the clothes together with the parents. 4. Exercise for bladder function: Drink more water during the day and try to prolong the time of urination when you want to urinate in order to train the bladder to expand. Children should seek professional medical help when bedwetting occurs, and choose the appropriate treatment under the guidance of the fish=doctor.
