Bladder-stretching exercises are done to help increase the amount of urine that the bladder can hold (bladder capacity) and to teach the child to hold urine for longer periods of time. To teach a child bladder-stretching exercises:
Children who are known to have small bladder capacity may stop daytime accidental wetting by using this method. For children who wet the bed, this method may reduce the number of times the child wets (or needs to get up to urinate) during the night and may help the child in the long run, but usually it will not produce completely dry nights in the short term.
It is difficult to know whether a child's bed-wetting is caused mainly by a small bladder capacity, although a health professional may use tests to determine a child's bladder capacity.
