As Clover said, everyone reacts in different ways.

Steph used to get eczema (mainly behind the knees and sometimes on the wrists/inner elbow), and I would use the dermaveen cream (relatively lightly) after a bath with QV oil (sorry, no bubbles). She didn't react adversely to the dermaveen or qv, and her eczema would usually be cleared in a few days of this treatment.

For really red raw eczema, I would use (very sparingly) cortisone cream. I'm sorry I can't remember what it is called, but you can ask for it at the chemist over the counter (well, it was last time I spoke to them). Once daily as required only. As soon as the eczema would settle down again to just being red, I would stop using the cortisone cream and return to dermaveen until gone. I don't know how old your DD2 is, but you may want to have a talk to the chemist about it.

Good luck, it can be a long road to finding something that works with your child.
