Bedwetting (nocturnal enuresis) is common and can be caused by deep sleep, a small bladder capacity, slow physical development, low levels of nighttime antidiuretic hormone, or stress. Please consult a pediatrician before giving any medication. Initial treatments focus on behavioral changes: limit fluids two hours before bedtime, avoid caffeine, ensure they empty their bladder right before sleep, and try a bedwetting alarm. If these fail, a doctor may prescribe medications like desmopressin to reduce nighttime urine production. Never punish your child, as reassurance and patience are crucial for their recovery.
