Hi - My DS is 10 1/2 mos. old. I started adding soy to my diet 3 mos. ago. DS had been ear infection free until 2 mos. ago when he had a Prevnar shot. I'm trying to determine if the soy to my diet or the Prevnar shot could be the culprit for his 4 back-to-back ear infections. Would there be enough components of the soy present in my milk to affect him?
