Is there anything out there I can use as a soap to wash my 2yr old up with, she has severe eczema and we have hard water. Hydrocotizone doesn't work.

Natural soaps. Try natural soaps such as dr. Bonner's castile soap--unscented or scented; also you can try to limit the length, duration, and type of baths. Shorter cooler baths less often help to maintain the moisture in the skin.
