I have a sensory seeker, which means I have a kid who loves to move and groove. She loves to jump, swing, run, body check me, be squeezed–anything that provides input to her body, she craves. When she was a toddler, she would run around the house clutching an object in each hand and hum a very low guttural hum. It took me quite some time to realize that she did that because the vibration she could feel in her chest from that particular tone felt good to her.
