This is an amazing talk about meeting your child where they are – that means encouraging and working on the talents and skills they have, following their lead and developmental timeline, and presuming competence at all times.
This also means not restricting or taking away their “obsessions” or “fixations.” This means not comparing them to others. This means caring less about how they “function” and more about what makes them excel. This goes for all children, not just autistic or special needs.
When you support them and their interests and accept them for who they are, not only will they flourish personally, but they may even devote a wonderful TedTalk to you one day.
