As added protection from wetness, you may want to get some underpads for the bed, because if there is an accident it is very difficult to dry a mattress. You also want to keep down the odor that could occur. Even using an adult diaper may not offer all of the protection you need. Sometimes things like that leak, especially if you are moving around a lot. It’s just a good idea to take that extra step to make sure that you stay dry and comfortable.
