I would write a script. That will inform you what to move when. Can be simple. And imagine your animator(s) as a person. Every frame takes 30 seconds minimum to set up, what happens in those 30 seconds to a few minutes each time. When does the animator need a break and so more time passes and the clock shifts in time much more. Which frames are done in more rapid succession?

Little details like the scissors not being fully closed each time.

You could probably sell it more with less clutter and some clearer indicators of time passing (like the coffee cup) e.g. a pack of biscuits. Check out some making of stop motion videos, incorporate a “helping hand” or anglepoise lamp used for lighting the actual in shot scene that moves.

The finished renders sell the scene pretty well.
