We will consider the nature and extent of any adaptations that you use to enable you
            to function. Such adaptations may include assistive devices or appliances. Some adaptations
            may enable you to function normally or almost normally (e.g., eyeglasses). Others
            may increase your functioning, even though you may still have functional limitations
            (e.g., ankle-foot orthoses, hand or foot splints, and specially adapted or custom-made
            tools, utensils, or devices for self-care activities such as bathing, feeding, toileting,
            and dressing). When we evaluate your functioning with an adaptation, we will consider
            the degree to which the adaptation enables you to function compared to other children
            your age who do not have impairments, your ability to use the adaptation effectively
            on a sustained basis, and any functional limitations that nevertheless persist.
