Most of us think of five senses and the human body: Sight, sound, smell, taste and touch. But, when it comes to learning to eat a wide variety of foods, two other sensory systems also come into play: The vestibular system and our sense of proprioception. As children grow, they are constantly processing sensory input, comparing it to other information stored in the brain and making decisions on how to react to that input. When it comes to trying new foods, all seven senses contribute to a child’s willingness to explore and try new foods.
