+1. We also have zero allergy history in our family.
My DC1 had terrible eczema and it didn't go away until we figured out he was allergic to soy (which was still present in the Similac Organic milk-based formula we used to supplement, and, it turns out, almost all formulas). We switched to hypoallergenic for a few months and I did an elimination diet and then when his skin cleared up we took him to an allergist for confirmation.
My DC2 has no allergies or eczema at all.
My sister's new baby also has eczema and, based on my experience, she took her to be tested for allergies at 5 months. Her baby is not allergic to soy, but is allergic to dairy and eggs.
Good luck, with whatever your baby's situation is, and getting it under control.
