Hi Cat,
I know the worry but stay positive - the way that you are doing it is great - a 6 week trial. My DS skipped two grades last year and I spent our summer vacation crippled with fear and worrying about the worst case scenarios - actually it turned out to be the best year that he has ever had at school. There are lots of success stories out there and you are going about it in such a sensible way, so have faith!
