Ever since a dermatologist told me in 2003 to use Dove Body Wash for sensitive skin, it's what we use. Walmart makes an exact duplicate generic brand under the Equate name, and that's what we try and buy, but they are often sold out. Either one isn't that expensive, about $3.50 a bottle or $5.50 a bottle and it sits on the shower shelf easily and doesn't slide off like a bar of soap or drip down. It works great.
