DD has a little rash on the back of her neck, it's like tiny red dots in a bit of a strip across her back kind of between shoulders but up a bit higher. It doesn't seem to be worrying her, but I just freaked a bit when I saw it! She had a few spots there last night but there seems to be a lot more tonight. It has been quite warm weather here for a little while and she has lots of hair. The back of her neck often seems a bit sweaty when I get her up from a sleep, would it be a heat rash?

Is there anything I can/should do to treat it/make it go away?
