Oh wow Lulu, I can understand that... I'd have to say in our case too that DD is beginning to purposely push his buttons (although i need to accept that is normal sibling behavior too), but she's a very full on child...so it's not just DS's issue at all, it's defintely the relationship as a whole.

What sorts of things does your OT focus on WRT that? I guess thats a pretty complex question to answer though lol. We are not seeing an OT atm, as I'm pretty happy with the OT stuff they are doing with him at school. But I'm really crossing fingers this psychologist will be able to give us some good advice & strategies...
