Hmm... I would do my utmost to avoid anything that's going to gum up my nappies, even though I use a liner. With DS's latest bout, the rash was literally everywhere the nappy touched - across his lower belly, all over both bum cheeks, around the outside of his hips where the sides of the nappy wrap around... For us, a liner wouldn't do a thing to keep cream off the nappy. We've been using Magic Stick, which is cloth-friendly. I'd love to have another alternative, though.
