When I first picked up the two books I chose only the "Fed Up", because "The Failsafe Cookbook" looked just like another recipe book to me. But I was back to the bookstore a few days later buying “The Failsafe Cookbook” and it has become our manual for living ever since, and a permanent fixture on the kitchen bench! PS - the pediatrician was very pleased with my daughter's improvement and asked about the book, he had heard of it but not known anyone who had tried to follow it, so was very impressed when he could see results - Teresa by email.
