My 6 week old ds has developed some kind of rash. He's got the milk spots which I know are normal but he's got this other rash which goes from his cheeks, over his ears, behind his neck and down to his chest. On his face there are small lumps under the skin. My HV looked and said it was normal, something about my hormones, etc. HTought it might be heat rash. When he's pushing out a poo and goes red all the spots are much more visible. What the bleeding hell is it? It doesn't seem to be bothering him....?
