Does anyone know what this is? My son broke out on his arms and legs today ONLY it’s not on his stomach/chest nor his back or face.. just his arms and legs.. this is the first time he broke out. He usually gets bumps on his shoulder part but not like this.. he didn’t eat anything new.. he does have a dairy allergy but he’s never broke out before cause of it he’s been eating dairy foods and I’ve been trying to get him off whole milk and switch him from whole milk to non-dairy(it’s hard) today he ate ice cream w/out me knowing from his grandpa.. he usually eats the Oatley ice cream could it be cause of his dairy allergy now? I’m making an appointment w/the pediatrician tomorrow morning to get this handles ASAP!
