When your foot falls asleep, it's hard to feel just exactly where it is, and it commands your attention. You need to move it, stamp it, and stamp it again to clear that strange tingly feeling. If you walk before the tingling clears, you may feel clumsy, or you may walk on it tentatively. If you're somewhere you can't give that foot a good stamping, the desire to stamp is probably all you'll be able to think about. If your child has sensory integration disorder, this may be what he feels like much of the time.
