I have a 6 month old that get flat red spots on the top of his head only( no where else on his head/face or body). They come and go, some times worse than others. They don t seem to bother him, no itching, fever or anything like that. I do not know where they came from they started a few months ago and as I said they come and go. His general peds Dr. saw them when they weren t bad and I showed him a picture of when they were at there worst. He said he had no idea what they were. He is growing fine, no health problems.
