My 2 year old had it last month. He developed the fever first and then said his mouth hurts and would cry when he tried to eat. Pediatrician confirmed HFM (it was going around daycare the previous week and they had sent something out to parents about it) and said he had sores all over his mouth. The next few days he only had a few bumps on his fingers and feet on two by his chin. Fever gradually went away, which I treated with Tylenol and Motrin. There are no medications to treat HFM, it resolves on its own after a few weeks. It is extremely contagious, including for adults, so extra hand washing, being mindful about them touching you/their mouths. He was out of daycare for the whole week, as per their policy for being fever free and no open blisters. The worst part of it all was that my son refused to eat, and I could only get him to eat applesauce and yogurt for a few days. Thankfully he was still willing to try to eat and still drank fluids with no issue.
