Lynn Mangan is a stay at home mom that became frustrated and scared when her son was not going to the bathroom every day. Allergies of animals, mold and other environmental factors were well known... food intolerance was new. We feel Brendan's story needs to be shared with young children who may be experiencing food allergies or an intolerance to certain foods that just need to be avoided. This book is not intended to diagnose or cure food intolerances. It is our story of what happened to Brendan.
