Primary school should be a time for learning facts and having fun. My six-year-old son has taken to checking the origin of food before we buy it. If it's not made in Britain, it stays on the shelf. Or it would if he had his way. It's not patriotism (he still clings to his Australian roots, just); he's just implementing the latest component of his grade 2 syllabus. Last month we couldn't flush the toilet more than once a day.
