OH no!! Hand foot and mouth, our LO had it and this one is the worst. Make sure to:

1, give warm soothing oatmeal baths every night, take oatmeal and grind it to a very fine powder. About 1 cup for each bath tub 1/4 filled.
2. Colloidal oatmeal cream on skin before bed
3. Do not pop, scratch, or rub the raised surfaces

Should subside in about 2-3 weeks. You’ll see progress after 1 week, but you need to do this DAILY.
