With bladder training, you "stretch out" the intervals at which you go to the bathroom. You do this by waiting a little longer before you go. For instance, to start, you can plan to go to the bathroom once an hour. You follow this pattern for a period of time, and then you change the schedule so that you are going to the bathroom every 90 minutes. Then eventually, you lengthen the interval to every two hours, and so on, until you are up to three or four hours between bathroom visits.
