I'm sorry about the problems you're having with your little one.

By any chance do you use fabric softener sheets or liquid fabric softener in your laundry? If you are, try not using it for a while to see if it makes a difference.
I had a dog that was very sensitive to fabric softeners of any kind, so I had to not use them on my bedding and places where she slept as she would get itchy.

I do hope you find the answer to the rash soon as it must be itchy for her....and frustrating for you!
