Epsom salt baths or other muscle soothing baths (before the pox errupt, a fever and body aches usually preceed). I wouldn't recommend this after they errupt, as it can be irritating
Depending on age, activities to keep busy when away from school/clubs/sports/friends.
Cool cloths, gel packs, etc for head/neck when your little one gets a fever
Witch hazel (diluted in cool or cold water) can help with the itching, and in preventing infection, as can pure honey and vitamin e oil. These can also help prevent scarring.
Tons of ice pops, juices, jellos, etc, to keep him/her hydrated
Good luck!

I tried for a few years before finally getting the magic shirt!
