With disposables, I've had problems with a rash around my waist. The plastic would cause itching, which leads to scratching, etc. To solve the problem, I have been tucking my undershirt into my diaper for many years now and it has really helped.
Has anyone else had problems with a rash around your waist, and do you tuck your shirt in?
I know it is at risk of someone seeing that you are wearing a diaper, but personally I would rather have that then the awful itch and rash that has developed in the past.
