I'm sorry to hear that your son is continuuing to react. :(
We visited an alternative medicine practioner today and she believes much of this stems from an overgrowth of yeast in *me* and that my immune system must be boosted in order to pass on decent immunities to my daughter, thus allowing her body to fight the eczema on it's own.
Does your son have a problem with yeast overgrowth? My daughter got thrush at 2 weeks of age and I've fought it with natural methods. But, supposedly yeast can present itself as eczema.
I'm sorry to hear that your son wasn't able to tolerate Neocate. My daughter is tolerating it, but I don't believe that it's best for her. And it certainly hasn't taken care of the eczema (I've considered an allergy to corn...).
