(HealthDay News) -- Bedwetting affects many young children and often doesn't indicate a serious medical issue.

However, the Nemours Foundation says, if bedwetting starts all of a sudden or is accompanied by these other factors, it's time to call a pediatrician.

• Bedwetting that resumes after a child has had dry nights for at least six months.
• Sudden behavioral problems, either at home or at school.
• Complaints from your child that there's burning or pain during urination.
• An increase in the frequency of urination.
• An increase in appetite or thirst.
• Swelling of the ankles or feet.
• Bedwetting that continues at age 7 or older.
