16 mo son has had a rash that covers his entire body for 4 weeks now. we were told it was eczema, not clearing up and getting worse. suggestions?

Rash: Without a picture it is difficult to give you a definitive diagnosis. However, if you claim he has eczema use moisturizer and more moisturizer. Apply at least four times a day and apply before bedtime. An antihistamine such as Benadryl (diphenhydramine) would be helpful for the itch. Since his whole body is involved i would not recommend steroids at present.
