... although if you had 450 books about Victorians for Fiveyearolds and you are now going to have to bin those and buy 450 books about The Stone Age for Fiveyearolds, I can definitely see that no matter the potential the stone age could be made for that agegroup, that's still really annoying.

Maybe there could be space for the Stone Age at some point in the curriculum though? I mean, I have a recipe here that describes itself as a 'paleolithic raspberry and coconut microwave mug cake', without a shadow of irony. :-D
