I don't want him to grow up

I am sitting here completing forms for T's nursery admission and I am feeling very sad indeed. Is it that time already? It is hard to think we have spent the last few years doing everything together and soon he will be off on his own embarking on newer adventures. Before I know it, he will be off to primary school, then high school, then college or university or a job, then move out... Oh no this can't be happening! How I wish I have the power to make time stand still
