we CD during the day and really love it. However I find that with every change my four month old has fairly deep (depending on the diaper) red lines on his legs and bum. They're not welts, just the kind of lines we all get from wearing socks, nylons whatever, too tight. This seems to happen to varying degrees with every diaper we use, from prefolds to all in ones etc. I'm wondering if this is normal or if we should be looking into other brands.
