C.P.
I didn't have quite the same problem but my girls both have terrible skin too. We have used every cream, lotion and wash under the sun too. What has worked for us is California Baby wash- can get at Target and a lotion called Cerave - Walgreen's. The difference w/ this lotion is that it contains no lanolin, and while lanolin is great for a lot of people, some do much better without. I am able to keep them 90% blister free if I put it on everyday after bath and when i find a rough dry patch. Hope that helps and good luck!
