The first few days of itchiness I put them in baths with goat milk powder and vitamin E capsules. With their food allergies, we just can't do oatmeal baths, so that was my substitution.
After three days of those I did have to wash them as they started to, well, smell like goat milk :-). But it was a nice, soothing treatment for those itchies. 
Between baths they were covered in a mixture of colloidal silver, lavender calendula salve from our wonderful friend at the local Farmer's Market, and tea tree oil. They probably would have smelled like goat milk sooner had the tea tree and lavender not covered it up so well! Uncharacteristically, Bella ended up getting them the least of the three. She had a few on her face and head, a few on her tummy and back, and some in her mouth and throat. That was it for her.
The older you are the worse the case, supposedly, but Max really got them the worst. Kane had the most pox. One day I sat Kane down to count the ones on his face and there were 45. Ugh. He was miserable.
But his didn't get as big and scabby as Max's did. And while Kane's seemed to just stop bothering him after about three days, Max had so many in his hair that his bugged him for much longer. At first I didn't want to admit how miserable it really was for all of us. After all, I DID purposely expose them to the virus. But I will freely admit now that there were a few days that were really hairy. Thankfully Bella didn't get them as bad, and hers broke out about 2 days after the boys, so that made it easier than it could have been. They all had them in their throats and mouths, though, which I think made them the most miserable. It was kind of cute, though, to ask Max to show you his chicken pox and see him hang that tongue out for you.
