I can't believe your rash journey TT. I have no idea what else to suggest. Have you given coconut oil a go? In the sposies?

I've been sending a few nappies to the compost :O We have used them to death, so off they go. I have one that I guesstimate has had 200+ uses, and it's only the inserts that are starting to look a little bit tired. I'm pretty proud of my stash, it has served me well. And the timing is perfect, we're winding back now that it's just one in full time cloth.
