My child has started to spin. We have had the toe-walking, the hand-flapping, the no-eye-contact, but we never had spinning. Now John is compelled to spin and spin and spin. He spins until he’s giddy and falling down, dizzy. How do I shake the terrible fear that grips me when he gets going? The fear that he’s disappearing, and that I can’t follow. He still responds to tickles, to the physicality of being held by his mommy — but soon, too soon, wiggles and bucks to escape my embrace to return to his spin, spin, spinning. So happy, smiling at something I can’t see. Will I see it one day?
