Using Dynavox T10 to learn to accept being told no!

So Kreed knows exactly how to ask for what he wants on his device. However in the past he was not great at accepting no. With the maestro we had to hide buttons, create pages to explain no etc. It was difficult and we never managed to help this behavior. With the T10 we have finally conquered this behavior! The T10 has so much vocabulary and so many different ways of asking for things, that Kreed will now exhaust every avenue and he generally seems to feel like he asked every way he can and the answer is still no. And now he will accept being told no without biting or hurting himself. He might cry. He pretty much talks to me for about ten minutes- just like a normal kid would beg for what they want. I find this amazing. And my number one reason for loving the T10. I dare anyone to find an AAC system with as much language as the compass software has in it. This behavior of Kreed's is a milestone for us- I was actually not sure if we would conquer this. But he has proven us wrong again and has done amazing!!
