As Trllian has allready covered a good description of what they look like. They are contagious until they scab over, and if kids go to CC, kinder, school you need to notify them and let them know and you will most liklely need medical clearence to send them back.

Both my boys got this last year. DS1 was much worse than DS2. DS1 had them all over hands and feet and also legs and a mouth full and poor thing ate nothing but ice cream for 4 days as everything hurt to eat, DS2 just had them on hands and feet and nappy area.

They can be on other areas apart from hands feet and mouth.

Hope you don't have too bad a run with it.
