I've been using coconut oil and haven't had any problems with my diapers. I have been putting it on my baby everyday since he had a blister type rash on his bottom, which it helped cure and we haven't had any problems since. I love coconut oil in general and use it for all kinds of things. I forget which brand I have, it's organic extra virgin that I bought at whole foods and I like it. (I prefer the extra virgin). I've heard nutiva is good and it's a good deal on amazon. That's actually what I plan on buying when I need more. I hope that helps!
