Chicken pox

Callie
My little baby girl has chicken pox. I feel so bad for her. It started out as a bump on her shoulder and on her arm. Then the following day more on her back...belly..side...and now she has a bunch on her head and some on her face. I didn't think a baby could get them. She ended up getting them from her Grandpa who had Shingles recently. Has anyone experienced this? How can I keep her comfortable other than Tylenol for her fever? How long do they normally last?
