My 14 mo. Old get red blotchy skin on her back/tummy when taking a bath? I tried using warm water w/no soap & it still happens. The spots go away after

Urticaria. Your child may be demonstrating urticaria (hives) because of exposure to the warm water baths. This is known as cholenergic urticaria. Try using cool to tepid baths instead of warm water baths. You may also give her one half teaspoon of Benadryl (diphenhydramine) before the bath if necessary.
