A few days ago, Baby V came down with a bug. Her nose ran, her appetite disappeared and her little body radiated heat. Over the course of a rough night, mean red spots cropped up on the sides and bottom of her feet. A little later, we found similar blisters on her hand. And then, as veteran parents might have suspected by now, we saw blisters around her mouth. Her rash eventually spread, but that initial pattern cinched the diagnosis, our doctor told us: Hand, foot and mouth disease.
