My 5 month old has got this rash over most of his upper body and down partly on his legs. The main areas are his chest and neck. People are telling us varying things...heat rash, food allergy, etc. The big thing is, it doesn't really seem to be bothering him too much. He's irritable, but we think he's got some teeth coming in. Without going to the doctor (which we will if it gets worse and or it seems to be irritating him) does anyone have any home rememdies or things that have worked for them? Parts of it seem to be really dry, almost like sand paper.
