I went through this with my son as well! He suffered until he was about nine months old. That's when I took him to a pediatric dermatologist. If I had it to do over, I would have taken him to her immediately. One visit and she prescribed medicine that cleared up his rash in two weeks. Her name is Dr. Robin Carder and her number is ###-###-####. You will be so glad you went straight to a specialist!
