Such events include angry parents, unfamiliar social situations, and overwhelming family events such as the birth of a brother or sister. Incontinence itself is an anxiety-causing event. Strong bladder contractions leading to leakage in the daytime can cause embarrassment and anxiety that lead to wetting at night. Some of the same factors that contribute to night time incontinence may act together with infrequent voiding to produce daytime incontinence. Sometimes overly strenuous toilet training may make the child unable to relax the sphincter and the pelvic floor to completely empty the bladder.
Most urinary incontinence fades away naturally.
Natural body alarms become activated. An overactive bladder settles down. Production of ADH becomes normal. The child learns to respond to the body's signal that it is tirne to void. Stressful events or periods pass.
