I agree with Lisa on the Cetaphil which I also happen to layer, though under another lotion (Dermal Therapy Urea/AHA body lotion).
However as Erin asked about the ingredients of Aderma Exomega Body Cream, I just looked at the ingredients (its in this link: http://www.garden.co.uk/acatalog/Aderma_Products.html
) Libby, if Pierre Fabre was not able to direct you, you may want to try Aveeno's colloidal oatmeal *cream*. Though not identical to Exomega, the ingredients are not too dissimilar and its effectiveness may be comparable. Just a suggestion after I looked at both sets of ingredients. Both use colloidal oatmeal (Avena sativa) and glycerin as primary ingredients so Aveeno may work for your daughter as a substitute cream.
