The first step in implementing a discrete trial training potty training program is to collect some data. Start by checking your child’s diaper every 45 minutes to an hour just to see if he has eliminated. Record this data until you get an idea of how often your child is going. Once you’ve determined the child’s average potty interval, take that number and multiply it by .75 for your timer interval. For example, if your child eliminates every 40 minutes, you would set a timer every 30 minutes.
When the timer goes off, you should have some kind of communication to indicate that it’s time to go the bathroom. This could be saying “potty time,” or if the child is nonverbal, try using a sign for toilet. Whatever signal you decide to use, make sure it is consistent and that all caregivers use it routinely.
