My daughter had them at 3 months old. She did fine. Yes, they do come in crops of spots. Lasting about 2 weeks which is when the last one is scabbed and therefore supposedly non infectious. Are you sure you need to bring her to the dr. and expose others to chicken pox? Zenya only had a fever for the first 2 days. She was miserable with itches but did very well. We did not stress dose but did all the normal things for chicken pox. Good luck! Oh yeah, I believe you can have a mild or severe case of chicken pox. My daughter’s was severe and started on her head and that’s where she had most of the spots. They do blister, too! Julia
