The Sequential Oral Sensory Approach to Feeding (SOS) introduces the 32 steps to feeding for children with feeding difficulties. This book reviews the SOS approach and its effectiveness in helping children increase the number of foods that they will eat. Most children started the program with a repertoire of less than 10 foods and increased the number of foods they ate over the three month treatment plan. This program focuses on introducing foods, textures and smells to children in a systematic manner.
