My child has really bad eczema. what's the best treatment to calm it down?

Moisturize: Frequently moisturizing, using mild soaps, bathing infrequently, humdifying the air may help. If it worsens consult your doctor for medications and testing if needed.

Topical meds: skin hydration and moisturizers are the most important parts of controlling eczema. This includes reducing bathing with harsh soaps and shampoos. Also avoid detergents with perfumes or colors added. When eczema flares up, you may also need a topical steroid cream in order to control it. Eczematous skin can also get infected, so if it looks bad, please see your regular doctor.
