Hi Jenny,
I'm not a doctor or a medical professional and all that warning stuff... :) Specific to being safe for a nursing mother, I would say that if the amount being used for yourself would be safe to use on or with a baby... by the time it gets through your system and to the baby, it won't be of any concern at all. Better to try small amounts and be on the safe side.
I don't have any suggestions beyond what you have already listed for immediate relief. I do however have a video from Dr. Ken Berry that I would like to share on Insulin Resistance/Metabolic Syndrome/Hyperinsulinemia. Eczema is around 7:45. I watched this video a while ago, and your post reminded me of it. He talked about how several skin conditions are being linked to insulin conditions and how a change of diet can help. It is interesting how your eczema got worse during a time with lots of cake and whatnot, because he suggests cutting out carbs as a way to help with the insulin resistance which in turn would potentially help heal skin conditions like eczema and others. He links to a bunch of studies in the notes. He has some newer videos specifically on Eczema that could have further information. It might be worth a try anyway.
