This is for all of you that have asked what plastic or rubber pants are for. They are used over diapers for added protection against leakes. You put the diaper on normally, and put the plastic pants up over them. Once you have them on, if you leak they will trap the wetness in between the diaper and your plastic pants instead of just leaking onto your pants. They deffinatly work as they have saved me from embarassing leaks in public several times. However, if you leak badly they will allow the wetness to get out. They also help cut down on the noise or rustle of the diaper. The only downfall is that they can trap in heat making the diaper uncomfortable.
Rubber pants are exactly the same except they thicker and are made of rubber. I have found that they are even better at protecting you against leaks then plastic pants. The only downside is that they trap even more heat then plastic pants.
Well I hope this answers any some of you had regarding plastic and rubber pants.
