Chicken pox

My baby has chicken pox! I feel so bad for her. She got them from her grandpa that ended up having Shingles. We didn't know that shingles leads to chicken pox in people who haven't had them before. It started out at as little bump on her shoulder and one on her arm. Then the next day the little bumps are everywhere. Has anyone else experienced this with their little one? How can I keep her comfortable other than giving her Tylenol? I hope this passes soon.
