Maggie,
I totally feel your pain! There a few things that I rotate through out the fall and winter months when my son's and my eczema is out of control.
*Gentle Naturals make a great body wash and lotion that we both use.
*Aveeno makes a whole infant line that is creamy and fantastic for treating dry skin. I use their creamy infant wash for me and my son year round and it's amazing.
*California Baby also has some really great products.

Here's the thing for my son and I, after visiting dermatologists we were told that cortizone only helps for when it's flaring up and at it's worst. Maintenence is key. Find a good routine that works. Make sure when you are bathing her to use something with oats that is non-drying and don't scrub the affected areas. Apply whatever lotion you choose immediately after bath is over.
It tooks me a few weeks to find something that worked for us consistently, but I can't use products made by Eucerin because they are very heavy and too much so for my skin as they did cause breakouts in other areas.
Unfortunately, there is no cure for it. And, I've lived with it my whole life. Also some suggest eliminating dairy products and adjusting diets to help minimize flare ups. If you can get into a dermatologist I would do it.
Good Luck!
