In preschool, stick to real time

Memento was a great movie, wasn’t it? And who didn’t love Godfather Part 2? But we don’t jump around chronologically like that in preschool. There is a very good reason most of the top preschool shows take place in real time, hardly ever even moving on to tomorrow, never mind shifting backwards to yesterday. If 24 had been a preschool show, nobody would have noticed what was different about it.
Generally in preschool, it’s good to stay in the present. Right now. In real time.
Young children don’t always have a clear sense of time. And the younger they are, the harder it is for them to understand. Children live in the moment. They live now. Yes, some actually have surprisingly great memories (like my eldest daughter) but it can be hard to process any true sense of when something really happened. A child might say “yesterday” and that could mean yesterday, last week, last year or five minutes ago. And without truly understanding how the past works, it’s incredibly difficult to really grasp the idea of time in the future.
Back in the early Fluffy Gardens episodes, I made the mistake of writing in too many ‘next day’ transitions. Rookie mistake. Much later with Planet Cosmo, it all takes in real time except for a single story which revolves around bedtime and so required one night-to-morning switch. Making it work took a lot of thought and, even then, I suspect I only managed to get across what was key to the story (bedtime) rather than fully getting across that passage of time, at least with the younger children.
It is okay to do that. You can tell stories like that as long as you know why it is you’re doing it, understand what elements are important to your story and make it absolutely clear, with the understanding that young children are not going to have that same sense of time passing that you do. But unless you really have to, I would always advise staying in the present. Stick to real time. It’s much easier for a preschool audience to grasp and they will be with your characters every moment of your episode.
