Carter's Mysterious Rash

After visiting two different doctors offices (one visit consisting of 2 different doctors inspecting Carter's rash) - they diagnosed it as Papular Acrodermatitis also known as Gianotti-Crosti Syndrome - sounds way worse than it is. Get this, when I was about 9 years old I had the SAME thing. Weird. Mom said it took about 10 different doctors to figure it out all those years ago. Apparently it goes away just as quickly as it appeared (usually after 4 weeks). The doctors assured me it is not contagious, and Carter is okay to attend daycare, etc.
