I did the same when my step-dad had it. Takes a while to get used to it all, when he had the operation where they removed his voice box etc, it took a while to be able to understand what he was saying. - Being scottish, he got annoyed that no one could understand him, especially when he had to talk by pressing the thing over the whole in his neck. Also the looks you get in the streets etc, soon get used to it all. As Dave said, just try and keep things as they usually would be, you'll adapt to the fact that he has it, and just make the most out of the time you have with him. I barely got to see my step-dad when he was in hospital, due to being at school, or my mum going straight after her work, but it was nice when I did see him, just to go and see him sorta thing.
