Nappy rash help please!

Hi ladies, I'm in desperate need of some help! My DD (6months) has started getting terrible nappy rash on her inside thighs and bum. She's been in Fuzzi Bunz full time since birth and was fine till about a month ago.
I didn't change anything (that I know of) so not sure what's causing it. She's still exclusively breast fed, and I change her 5-6 x daily.

I've tried a few things to get rid of it:
- stripping the naps with lots of detergent-free washes/rinses
- changing from ecostore liquid to surf sensitive powder
- doing an extra rinse after wash
- giving her more nappy-free time
- switching to softer mio bambino liners

BUT none of seems to be working!!

I'm trying different natural creams
- Tui baby balm and Weleda nappy change cream, which don't do much to clear it up. It only thing that does work is a prescribed cream with hydrocordizone which I don't want to use regularly!

Anyone have any ideas? Can I use bepathane, or will that affect the nappies? Should I apply aqueous cream or oily "fatty cream" to that area or better to keep it dry?

Please help! I'm sure it would clear with disposables but I'm loathe to stop using cloth.

I've been using Little Genie disposable wipes. Maybe they're too astringent? I have chux cloths I'm thinking of switching to, or maybe i should use a more natural disaposable wipe? Will take advice to only use for poo. Thanks!

i didnt know surf did a sensitive...

how much washing powder do you use? and have you tried without the liners? also have you checked with the doc it isnt bacterial or something other than a nappy rash?

I use muslin wipes with just water on at home, and DD came out in a horrible rash in her second week at daycare because they were using their wipes on her (I'd said it was ok for them to try them) so now I send her with muslin wipes as well as cloth nappies and she's all good again. Her carer thought it was a teething rash so that must look similar. Plunket also saw it and suggested a food reaction - have you started eating something new? Perhaps a fruit thats come into season?

I use microfleece liners with nappy creams and that seems to work too.

I used surf sensitive powder when first stating out in cloth. It was terrible for the nappies, they stunk of wee and Jody got a nasty rash. I then changed to Am-O-Lin liquid and have never had to strip them again.
Also, when Jody was cutting her front teeth she did get rashy. I use sposies overnight so I could lather her up with vaseline for bedtime which seemed to help.

A quarter scoop for half a load does sound quite a lot. For a full load of clothing I generally only use about a quarter scoop.

For my nappies (which is generally about a quarter load at a time) I use about half a TBSP and then do an extra rinse cycle at the end.

Definitely be wary of the little genie wipes if she's got sensitive skin.
