Analogue here. DS knows the big hand is at the top and the little hand is at the number for an "o'clock" but TBH I'm not pushing it. I can tell him where the big hand will be when dinner is ready and that quietens all questions (or did until DH packed away all the analogue clocks until we move: I now have to take off my watch every evening so DS knows when food is ready).

We do have a Spot the dog DVD packed away somewhere with a 15-min telling the time episode. It looked pretty straightforward but it will be in a box for the next 2-4 months so I won't be able to give any more info on that. We also have a jigsaw clock we play with.
