Hi, my son is 4 months old and exactly 2 weeks ago a doctor told me he had chickenpox, he also had a rash all over his body which the doctor told me was due to him having chickenpox. I'm just wondering how long it takes for all the spots to come out as he is still getting new spots I noticed another lot under his arms and one on his neck, for the past two days his temp has been up and down but this is the first time he's had one in the whole two weeks. Just wondering if anyone else has experienced this with there baby?
