Rash? Chicken pox?

Desiree

My baby has had red spots and blotches all over her back for the last couple days, then went away for a day and came back and is now spreading to her stomach and head/face I’m not sure if it has been bothering her but she has been a little sick these past few days. (Cough, running/stuffy nose, sneezing, unable to sleep very long) her behaviour hasn’t changed but she has been a little fussy with eating.

There was one night she had a fever of 101 but has not been that high since.

I’m not able to take her to the doctor as it’s a few days from Christmas and it will be atleast a week before we can see a doctor.

She is 7 months and breastfed. She was eating rice and oat cereals but no longer eats or finishes her bowl.

I’m a ftm and I’m worried that it’s something other than just a detergent rash or a heat rash. Could this be chicken pox? Measles?

Is there anything I can do?
