Childcare: Neocate

Soy Milk for 15 Month Old

My 15 month old had a milk protein allergy and was on Neocate until 12 months. Since then he started milk and has done well. However, he now has ezcema. Not horrible but enough to cause discomfort. I was thinking of trying Soy Milk for him to see if that helps his skin clear up before going the meds route. Anyone ever have experience with this or have you done Soy milk for your child? Thanks.
