Rather than make a question I thought a wiki would be better for this. (Hope I can convert it later).
My wife and I are more apt to try and prevent things from happening to the kids, and diaper rash is one we've been successful at preventing. Although I haven't heard many other parents talk about it since there isn't one here that talks about prevention I was hoping we could share what has worked.
I'll add our strategies to this wiki these have worked out well with our two boys, and some of the first advice I give to new parents who ask for tips. If others have workable suggestions I hope you will share!
