Early Intervention (EI) Therapy is a passion of mine. The NDIS currently supports young children from zero to seven years with an Early Childhood Intervention Services ECIS model without needing a formal diagnosis.
As explained further in an American Occupational Therapy Association article by Ashely Opp: A child’s earliest years are filled with new stimulations and novel experiences that drive their cognitive, social, and physical growth. The first three years of life are a critical time for brain development, significantly if a child is delayed or restricted in development. If a child needs support to develop optimally, occupational therapy can help.
Furthermore, occupational therapy aims to assist children with developmental delays or a known physical or mental condition associated with a high probability of delays by improving their motor, cognitive, sensory processing, communication, and play skills.
