i know of alot of babies with horrible nappy rash and they also use cloth nappies and don't want to use the creams, but sudocream really is magic, for the sake of your bubba just use it for a couple of days and use the disposables. We use band aid's when we have a sore, use disposables when your daughter does.
I used to use disposables but this still happened to her bum! I also have tried sudocrem despite her being in cloth and it hasn't helped (and bepanthem).
Re thrush symptoms, this isn't persistent and starts to heal straight away as long as she gets lots of air on her bum. She has also never had oral thrush (I kept an eagle eye out for it because she spent such a long time being rubbish at latching).
Oh I forgot to say that I don't use wipes unless away from home (vacation etc.)
Summer rain: did you self diagnose the acidic food thing or is it something health professionals are aware of?
