Some things to consider as you go through your journey:
1. Understand that autism is a genetic/epigenetic, prenatal, neurodevelopmental condition that affects the anatomy and physiology of the brain, as well as, physical coordination, the sensory systems, the endocrine system, and immunological system. The psychological and psychiatric components are secondary.
2. We are quickly approaching the crossroads where autism can be diagnosed by a neurologist via neuroimaging and testing. Right now, it is still within the realm of the diagnostic statistical manual (DSM) and the psychologist. This may change within the next decade, or so.
3. The brain is in a constant state of change from an infant, toddler, small child, teenager, adult, to geriatric adult. The genetic components and resultant autistic symptoms will change over time. There are those of us who present with obvious autistic traits early in life and receive an early diagnosis, and those of us that might not receive a diagnosis until much later. The presentation is highly variable.
4. A child's brain has an extremely high level of neuroplasticity. Our intelligence (ability to learn) is actually at its highest when we are small children. Many psychologists who understand this will tell you that most of us quite literally have genius IQs as small children, and then our parents get in our way!


To be clear, as a small child, our understanding of our world, our knowledge is very low, but the brain's capacity to learn is at its peak. If there is ever a time to spend with your child on learning and exploring, this is the time. Engage in life skills (cooking, cleaning, fixing things, gardening, etc.) Most parents hold their children back under the excuse, "They are too young.", not knowing that by the time they are "an appropriate age", their ability to learn has diminished significantly.
