Hi NC yes that's me
thanks for all the responses...lots to think about, I appreciate your advice and experiences.
Cargirl, Good idea about the camera, we did this a while ago when I went on a trip and he stayed with my mother. He was very clingy after that though, and still is at the moment so I'm thinking that Nickschick may be right, it could instigate a setback instead of a sense of achievement.
I didn't used to know whether to believe him or not re his reluctance to do things. However I spoke to him yesterday about this trip, (his having already mentioned it, it was too late to avoid the subject) and asked him honestly whether he would consider going, because I thought it might be good fun with his friends on the train etc. I tried to make it sound good.
He came right back with 'No, I don't want to go.' So I asked gently why that was, and he said 'I only want to if I had one adult by myself,' and he said it in such a clear, thoughtful and serious way that I felt perhaps for the first time, that he really knew what he was on about and what his own limits were.
So I told him that that was fine, there will be plenty more trips and I understand the rite of passage thing but he just doesn't feel ready yet. I think there comes a time when you are ready to place yourself directly in the hands of your friends and teachers, but for ds at the moment it's too uncomfortable so I'm not going to push him.
Thanks again for your help, it made it clearer for me about the various angles I needed to take into account.
