I tend to wear plastic pants over my disposables. I know they'll not stop a bad leak but they can be great at catching the little ones and stopping those annoying little wet spots.
Part of the reason for wearing them is that I like the extra feeling of security gained from knowing that there is a second line of defence between me and my trousers. They also tend to help me to regress better too.
I'm just curious if anyone else tends to wear plastic pants over their disposable diapers and why?
