pediatric allergist in Chicago, Indianapolis, or st Louis. GAPS knowledgeable!!!!
I have one in Geneva Illinois who is great- breastfeeding friendly. I don't know if she knows about the GAPS diet, but I do know she is seriously the most knowledgable MD i've ever met vis a vis breastfeeding- seriously, she's not an OBGYN or breast health, but she knows a TON about it. :)
That and she answers the phone occasionally instead of her secretary- and calls you back PERSONALLY. PM me if you want her info!
