Poor baby girl!

So Friday morning i got Kaydence out of bed and i was changing her diaper and she had really bad diaper rash. It was really red with big red spots on the inside of her leg. I was worried so I had my mom come look at it and guess what she said they are... chickenpox! I started freaking out and took her to the doctor. The doctor said that she couldn't tell 100% if they were or not. So I am utterly confused... She gave me some cream and said that if it didn't help the spots then they were chickenpox. Oh and yes she did get the vaccine at her one year appt but there are kids that can still get it. Lucky us!! :( They are already healing so either the cream worked or if they are pox then they are almost gone because the doctor told me what they'd look like when they heal. Still utterly confused... I have no clue where she got them from but hopefully it'll be over with and one less thing to worry about later on. Just to be on the safe side the doctor said that I should keep her away from others for a week or so. So sorry but I hope this explains why i haven't done friend or neighbor Christmas presents yet. Hopefully I'll get to it but if not, I am so sorry. :( If anyone has any advice or can sympathize with me that would be great cuz I feel like the worst mom in the world right now. :(
