Hypnosis can help children overcome aversions to certain materials by addressing underlying sensory sensitivities. Through guided relaxation and positive visualization, hypnosis encourages children to reframe their perceptions, gradually desensitizing them to uncomfortable sensations. By fostering a calm and receptive state, hypnosis enables children to explore new textures and sensations with greater ease and comfort. This process can lead to increased tolerance and acceptance of different materials, enhancing their overall sensory experience and reducing discomfort.
