I found out that my son had Hand, Foot and Mouth Disease because I had put him to bed. I went to feed him in the morning, it was about 7:30, he was on fire. His fever was so high, that he was hot to the touch. It was very scary, as he had never been sick before. I knew right away instinctively, that I need to call the doctor. It was on the weekend, so I called and because of the particularly high fever -- it was running 104 or 105 -- which was very scary as a new mother. We ended up taking him into the doctors office. She did the check up and flashed a light on his throat, and, lo and behold, there were about 30 blisters in his throat. It was bright red. I almost gasped, but also, there was a sense of relief because I knew it was definitely something. It wasn't just a fever from teething or something, but it was also curable.
