What's the law on car seats for under 10s?

My grandson knows how tall he is… . “Nanni, I’m the same height as an Emperor Penguin.” he told us yesterday … seems he is moving class, into Penguin 4 in September and has been exchanging info with his new Form Teacher…

So, we now have to explain to the Emperor…that he still needs to use the seat…:frowning_face: but perhaps he won’t mind … if we call it a throne instead…:heart_eyes:
