Missymoo - Yes, that is fungus, and it's damn hard to get rid of, changing liners won't help and the reason sposies are is because it's keeping all moisture at bay. Elly has had the EXACT same thing on and off for a few weeks now, red spots that blister and look terrible not at all like normal nappy rashe. It's not food or liner related with her either as I have nappies from about 5 different materials and I don't think at her age she's suddenly developed an allergy to all of them. I haven't done the canesten rinse yet, but what has helped immensely has been using the normal canesten/clotrimazole cream every nappy change she's in cloth for which is through the day (since it's a rub in clear anti-fungal cream you don't need a liner either) and at night when it flares up have had to resort to the sposies with the canesten + a barrier cream over it. The thing to remember with anything fungal is that one the sores disappear it's still there, so you have to keep up applying the cream for at least 14 days after the rash disappears and if you don't get canesten rinse use tea tree oil in the rinse cycle of your nappies to kill any spores in there.
