5 most common kid skin rashes and sensitivities (and how to soothe them)

Sometimes called contact eczema, contact dermatitis is a rash that appears after skin comes in contact with an irritant or allergen. It looks similar to eczema—red and scaly—but is more localized. Potential irritants include detergent, citrus or even a kid’s own saliva.

A common cause is nickel, which can be found in jewellery, belt buckles and even onesie snaps; other metals, chemicals and fragrances can also produce allergic contact dermatitis. The rash typically lasts as long as the trigger is present, but a severe reaction may need some help.
