I have developed hive-like bumps (which I've of course scratched until scabby) on my neck, shoulders, upper arms, and down my chest. At first I thought perhaps I was having an allergic reaction to a new allergen I was not aware I was sensitive to. Then it dawned on me that these are the areas on my person that my 4 month old most often drenches in spit up and leaves me little time or opportunity to thoroughly wash off with proper soap. Has anyone else experienced this?
