My DS (as/hfa) sometimes toe walks at home if he's got his shoes off, well up until recently when he decided that he didnt want his feet to touch the ground anymore so I had to buy him slippers to wear at home so he doesnt toe walk much anymore, but he's started shuffling his feet along the ground instead. He used to shuffle a little and it gradually become more and more and now he does it quite a lot instead of normal walking, even when he's outside now. Is his shuffling an alternative to toe walking or just one if his quirky little habits?
