Hello! I'm really glad to get to meet you. As someone who has SPD herself but knows how scary a meltdown can look from the inside and the outside, I can understand why it is so hard to have a child who so completely changes. Dan recently posted a nice article about meltdowns that might help give you a starting point to making sense of some of what might be going on in your son's head. And I agree with you, OT by itself may not be enough until you and your family and your son all learn together how to help him with his struggles with what sets him off. It can be very frustrating. But it sounds like you are making steps in the right direction for learning and growing towards better solutions.

If you have specific things that you know set him off, I'm sure people would be glad to share what helps them. Different people have different sensitivities or undersensitivities, so getting a handle on what his are should help a lot to start.

I know it's frustrating. I'm glad you're here to share this with us. Together, I'll bet we can figure something out.
