I'm seventy six years old and been looking for a solution to diapers for elderly. It doesn't matter if you're a baby or how old you are. There is a need for some dignity in this area. I bought these several years ago when they were considered very expensive.But I thought it was an investment. Now I have several different brands and kinds for different reasons.But I love them all, and I still use diapers for those occasions when I need them. But I love my social life without diapers now.
