I do understand where you are coming from, we talked about coming to Australia for a long time before we actually moved over so the kids had always known that we would one day move, our then 9 year old was apprehensive about going but we explained it as an adventure and if we didnt like it after a few years we could come back, when our visa came through our 6 year old daughter sobbed that she didnt want to go because "they dont speak my language"! little things like that can stress out kids and when we explained to her she was fine with it, we have been here nearly a year and the kids all love it here, they instantly made new friends at school and we put them in similar clubs they had been in the UK so they could make friends with similar interests. Hope this helps.
