Tell you child what you expect of him. Have an alternate plan that you may or may not tell him about. Maybe you will need to take him for a ride in the stroller during the game if he becomes restless, or take him to a playground and let him swing or slide if a playground is available. Swinging and sliding, plus riding in the stroller provides vestibular and proprioceptive feedback that is calming. Let me define those words.
Vestibular stimulation comes in through the semicircular canals of the inner ear.
It is the sense that is related to balance, gravity, whether you are moving or standing still, how fast you are going and in what directions and where your body is in space. The vestibual system maintains muscle tone and postures so you can move efficiently and hold your body in position comfortably. It helps to maintain a stable visual field by adjusting the eye and neck muscles to compensate for movement of the head and body. It enables you to use both sides of your body together and provides the foundation for higher level learning Proprioception is the conscious and unconscious awareness of where your body is and how, or if it is moving. The sensation comes in through joints and muscles.
