K.N.
As the mother of a 5 month old with allergies and eczema and skin that can't touch anything without getting covered in itchy bumps, I'd try cloth. It isn't expensive, and I find prefolds and covers work just fine. No need for the fancy stuff. I believe there is a site, miraclediapers, where you can get a started pack for cheap, they are used but it would allow you to try several different diaper types and I think you just pay for the shipping. it's a thought. Otherwise the cheap plastic pull on covers that can be used over cloth or training pants may help contain the mess from the blowouts and at least protect her clothes.
