Look Familiar?

Elizabeth

So its Sunday and baby boy isn't showing signs of being ill so I don't want to rush him to the ER for no reason. But he is only 6months old and these splotches just popped up outta the blue! Anyone have any idea of what it could be? Or if I should be ok till the a.m. to call his doctor? He is acting completely normal. So was hoping someone else experienced this b4.
