    ### Instruction:
    What is (are) Bedwetting ?
    ### Response:
    Many children wet the bed until they are 5 or even older. A child's bladder might be too small. Or the amount of urine produced overnight can be more than the bladder can hold. Some children sleep too deeply or take longer to learn bladder control. Stress can also be a factor.
