For those of you who have had LO's cursed with Hand Foot Mouth in the past, how long did the rash keep spreading and new blisters form? We're on day 3 and it's still slowly spreading. He had nothing on his face until just a few hours ago. I was hoping it would be on its way out since some of the blisters have popped and are drying up, but now I'm wondering if it's going to get worse before it gets better.
