S has the sort of skin that's sometimes a little sensitive. A while back she had some sort of eczema that eventually covered her whole body. We tried several different creams before we found one that worked. None of them made it any worse, and I had gloriously soft hands from applying it twice a day... but they didn't solve the problem.
Meanwhile, S loves to play with play dough of any description. I usually make it with corn flour and oil, but the oil can stain her clothes - she's a bit of a mucky pup, and it tends to get everywhere. Traditional play dough has a lot of salt in it, and can make her hands dry and sore quite quickly - which is not ideal as she doesn't like to have cream on her hands. I was delighted then, when I found this post on The Imagination Tree, for play dough for sensitive skin.
