At what age does involuntary urination need to occur to be classified as Enuresis?

Involuntary urination, to be classified as enuresis, must occur in a child who is at least over the age of 5. According to the DSM-5-TR criteria for enuresis, the diagnosis applies to children who have reached this developmental stage, as by this age, most children are expected to have established urinary control. The condition is considered when the involuntary urination occurs at least twice a week for a duration of three consecutive months, or causes significant distress or impairment in social, academic, or other important areas of functioning. By establishing this age threshold, the classification ensures that the diagnosis reflects an issue that typically would not be expected in younger children, who are still developing bladder control.
