My daughter is 4.5 years old, and she has a red rash on her bottom, behind her knee-caps on her legs, the thighs, and on her elbows and the crease of her arms.. It doesn't itch her, but it does have heat inside it. Any scented lotion aggravates the rash and causes it to spread. She doesn't complain of any pain with the rash. I put vitamin E cream on it or Vaseline, which over night minimizes the rash, and then turns it into dead skin, and peels off. Leaving a white skin, with no pigment in it. Please help! Shes getting older and it doesn't seem to be going away.
