Allergies and Breastfeeding

Amanda
My 5 month old was recently diagnosed with a dairy allergy. I cut out all dairy and dairy proteins. I now discovered he has a corn allergy as well. We are going back to his allergist in a week. He is so miserable and I feel helpless. Has anyone had success with their babies outgrowing allergies? I'm so worried he's going to be plagued with this forever. I'm willing to breastfeed him and eliminate whatever I need to for him to be happy. It's just difficult and I'm losing so much weight but he is worth it.
