I used sposies on my dd for the first year. She had a bad diaper rash for the first month. I asked her dr about it and he said it would take about a month to clear up, and it did eventually. Thier skin just has to get used to the acid, and in sposies all the mositure is sucked up, where as with cloth sometimes the skin is right against the moisture. I would sugest a fleece liner and give it a bit of time before going back to sposies. Hope that helps.
