I'm a speech-language pathologist with lots of experience, both personal and professional, treating sensory processing disorder also known as sensory integration disorder. A child who seeks out objects or clothing to chew on may be seeking proprioceptive input, which is stimulation to the joints, muscles and ligaments. It is recommended that you provide her with lots of heavy work activities, such as pushing heavy boxes across the room, moving furniture, as well as climbing and outdoor play tasks, frequently throughout the day to satisfy this need. She could also be encouraged to chew on some vinyl tubing or a "chewy tube", available from Super Duper Publications. I sometimes let my sensory kids wear a necklace with a piece of tubing strung onto it so that it's available for chewing. It's good to give her something appropriate to chew on so that she doesn't start chewing on her clothing or other inappropriate objects. Does your child have any hypersensitivity to touch, textures or sounds? If so, you might want to consult a professional. You can contact me if you wish through the California-Hawaii Elks Major Project.
