Strange rash

Hey mommas!

So my daughter has this "rash" on her back, and a bit on her legs and arms.. at first it was on her back and I belive it was baby acne, my doctor even said it looked like baby acne.. but now I have relized their is one spot that is more red, and rash like vs just little raised bumps.. also she has small patches on her legs.. I have been tracking all her food intake and there hasnt been anything that seems to make it "worse" I have used the same laundry soup since she was born. And nothing "new" forsay..

Do you think it could be allergies?

Or maybe baby eczema??

I will take her in if it gets worse.. but shes had it for a while..
