I have a 12 moth old baby. She started to develop what looked like a heat rash on her back about 2 weeks ago. The rash slowly spread to her chest and is very itchy. She wakes up at night scratching. I thought that she might be allergic to blueberries but the rash is still there even though she did not have blueberries for the last 2 days. Last night she also develop a flue. Could you please let me know Dr what this rash could be as well as any suggestions to the type of lotion that might be helpful for the itch? Your help is greatly appreciated thank you. Joanna
