Excema?

Ra

My sons skins became so sensitive. He’s got rashes behind his knees and in the creases of his arms. He seems to be breaking out in rashes all over. This has just started in the last couple of months getting worse. I’ve got a steroid cream and bath emollient from the GP but it’s not really helping. I’ve not changed washing powder etc. I’ve been giving him cool baths and keeping him cool. Any advice?
