Bring her back to kkh, you can go do the skin price test. I did it for my son. And managed to find out what the trigger is. Meanwhile, I stopped all QV, cetaphil, physiogel. I used ever ezerra and loved it however it's too costly for me. So now I stick with coconut oil. You can buy it at Watsons and even use the CDA. Vita coco coconut oil.
i went thru the same for my child, QV did not help so i experiment with cetaphil, sebamed and physiogel. physiogel works for my child
Have you tried to find out whats the trigger? Could it be something related to her diet?
