Wow, it's been very quiet on here recently! Hopefully means everyone is doing well.
brightstars I can't help you with AIT but others have definitely done it. I think it was talked about quite recently on the thread.
skewiff yes, we have it to the right of the screen as you look at it for both hemi p and t. Not sure if others do the other side depending on what part of the brain is being worked on, but Robin told us to do the right. Hth.
disorganisedmummy hello and welcome! Don't be apprehensive. It can only help! Robin is lovely and kids love him so good luck for your appointment. You could start the diet changes and supplements now if you wanted. Have you read the books? When we started (about a year ago), I remember feeling so relieved that I finally I could do something to help him. All the " professionals" had told me was there was nothing we could do. Anyway, good luck!
Things going well here. DS continues to thrive. His language and speech is just AMAZING! We are so pleased. Everyday there are new things, new words, more complicated, longer sentences etc. It has exploded! I would even go so far as to say that his language is almost at the same level as his peers. I am just so pleased! Now, if we could just getting him to start using it a bit more... 
He's still loving nursery and I think he is very slowly beginning to talk more there. I feel like I'm constantly questioning the nursery teachers as they don't see the same importance to his communication as I do. He isn't chatty but I know he's told them things like his Granny was coming to lunch one day. For me, that's big news as he is communicating for more than simply having his needs met but I have to eek the information out of them. I really don't think they see a fraction of his amazing speech that we do at home. I'm sure it'll come.
Following a few emails with Robin, we've now stopped the stairs for the moment. DS was really hating them and totally refusing to do them. He's become quite scared of the dark and I think he was really not liking having to close his eyes. He's has become more emotional all round. He's talking about feeling happy, sad, surprised, scared, and he'll tell you why. He was sad when we took the Xmas tree down, sad when his birthday party finished. This is all new ground for us and Robin was very pleased and said it was a positive step.
