How Do You Break a Good Habit?

When we saw our toddler twins using too much toilet paper, we enforced a new rule that they place all toilet paper in the trash and do not flush the toilet. This way, we could make sure that not too much paper was flushed. Now that they are older and understand proper toilet paper disposal, we can’t seem to break the habit. The trash can is always full and they leave “surprises” in the potty.
