L.S.
Sounds like you are doing what you can to help it. Have you considered the products you are putting on her skin - the clothes and diapers in 'free' detergents is an awesome start.
I have a niece that used the Arbonne Baby Care line. It is toxin free, no petroleum products or byproducts including mineral oil (baby oil) which is a major ingredient in all the lines you mentioned.
She went from skin problems to no skin problems in only a matter of a week or two. She was breastfed, too, and was doing everything you are except the cloth diapers.
Prices are reasonable as the products last twice as long as others - more concentrated. Arbonne also offers a membership that gets you a 20% discount year round, no hassles or pressure to sell it either.
I have news articles from msnbc and environmental working group about the major baby wash products being toxic if you would like me to email them. May help you to fill in your big picture of what the next step should be.
Many blessings,
L.
