How we work

The body keeps a budget

In shortSleep, hunger, illness and long days use up the body's energy, so the same request can cost far more on a bad day.

The idea

The brain manages the body’s energy by anticipating what will be needed: eating, sleeping, moving, getting through a task. When sleep, hunger, illness or days of effort weigh on this budget, the same request can cost much more. It is a useful way of thinking about why the same child reacts differently to the same thing on different days.

What to try

  • In the timeline, also note sleep, food and what happened earlier in the day.
  • Plan the hardest parts for when the child is rested.
  • Compare days: what was different about the days that went well?

The common mistake

Looking only at the moment of the reaction and not at the day that came before.
