You could try an oatmeal bath for the hand and foot part. Our DS had this a few months ago, and jello seemed to be a big hit. We could get by adding applesauce, but not much else for nutrition. Also, overcooked noodles seemed to be okay, either macaroni, or some other easy-to-eat shape. For us it was just about 2 or 3 days, if I recall. No one else in the family got it, but his older brother was old enough that it may just have been an age thing. If I recall right from my years in the drs. office, it's only of concern for pregnant women in their middle trimester. Otherwise, I don't remember the doctors worrying. Handwashing is the best defense in that area.
