You have given a good description of your children's rash. The important thing is that they have not been ill because one important cause of a sandpaper rash is scarlet fever.Fortunately we can rule this out. This leaves a much more common cause especially if your children have been well and that is a heat rash.No treatment is needed for heat rash usually,but you can apply a good moisturiser such as Epimax cream if their skin is dry and a bit itchy.The rash will clear up by itself.
