Since this, aned rubber treatement in genersl is about wetting, the big question is why use wetting? There are a number of good reasons

Wetting is embarrassing, When you wet, it means that there is something that everyone else has control over and you do not, and it is a basic part of being a "big girl" as opposed to being a baby that this control is about. So it makes you less than everyone else

Wetting is demeaning. It means that there is something wrong with you so you can be teased and made fun of. Even if it is not done to deamean a Little Girl, there is no escaping what it means when some other little girl asks "Why is Christine in all that rubber?", or "why does Christine smell like that?" or "Why does Christine's room smell like that and have all that rubber?" or, if you take her to someone's house and they say "I hope you are going to put a rubber sheet under her, I do not want the smell to get on the chair or bed or..." How would you feel if this talk was about you.

Wetting involves the Chastity area. The wetter needs to wear special, baby umderclothes on that part of her body that need to be changed which means someone has to get at her chastity area. That is the most private part of a girl's body and to have to have that area looked after by someone else ks kind of like being violated in some way. As part of this the person wetting needs to be dressed in such a way that it is easy to get at her chastity area. The best way to be dressed for that is in short, easily lifted skirts, dresses and babydolls. For a Little Girl This is especially horrid since her chastity area will be attended to by someone else and ath the time chosen by that someone else and since that humiliates and embarrasses Little Girl, that someone else is probably enjouning it

Wetting makes you smell. That usually leads to one of two things. Certainly nobody can ignore that fact so they notice you. Persons may want to avoid being near the Little Girl. On the other hand, the smell of wet makes some persons think of rubber. Again, some will try to ignore or avoid the Little Girl, recalling their own experiences with that material and wanting to stay far away from it , But others... When I smell dried wet, I think of how nice it would be to get my hands on the rubber. If a Little Girl smells like that, then I know she wets and probably is still in rubber panties. Since she is probably deliberately made to smell like that then her Mommy wnats it to be noticed. Also, if this is true, then the Little Girl most likely has a rubber diaper under a cloth baby diaper and Mommy wants what is about to happen to her precious little dolly girl.. I want to get my hands up under her dress and feel those scrumptious panties and if I am lucky she will have two pair on and I can get between them. This is just the start of something that ends up rather unpleasantly for her and since I am good at this, I can make it last a very looooong time.

wetting requires rubber so it is the perfect reason to use rubber on the person Some persons enjoy getting their hands on rubber so that is another thing that the person enjoys about the thing that Little Girl finds horrid. So Little Girl does not know if she is put in rubber just to deal with the wetting or if she is made to wet so that rubber can be put on her. Being dressed in rubber and in a way to make your body and especially your chastity area easy to get at have always been the way to treat those who are to have things that they do not like done to them. Also, rubber on the parts of the body that feel things the most and especially on the chastity area, feels unpleasantly strong and is very distracting and can be used to make a person wet herself

All of this is done in such a way that it is very easily seen or smelled

When you cnosider all these reasons, the real question is "Why not wetting?"
