Lots of kids continue to wet the bed at night even though they are successfully using the potty during the day. (Even at six years of age, 12% of kids wet the bed.) Most parents use Pull-Ups during this period of nighttime wetness to make the morning routine easier for everyone. However, most kids become dry gradually and many of them will still be in Pull-Ups even though they are dry three or four nights per week. If your child is dry at night, you do not need the Pull-Up away the next morning. In most cases, a child can reuse a dry Pull-Up five or six times before it gets so tattered or baggy that it needs to be thrown away.
