For various reasons, I would like to use a completely soap free wash on my children. I put Balneum in the water and know that should be enough to just use to wash them in the bath but they do need a bit more than that sometimes or in the shower. I thought I had found an Aveeno one but the ingregients still contain soap. Any ideas? I can't afford expensive and it needs to be like a "wash" i.e not the diprobase-type creams the hospital recommend.
