Spring and the design instinct. What children make when you leave them alone with it.

The spring design instinct in children is reliable. Every May, I watch it arrive. The bedroom that was fine in February becomes insufficient. The LEGO city requires a new urban planning framework. The garden suddenly needs zones. The child who has been living inside the existing arrangement for months sees, in May, that the arrangement was not permanent — that it was a choice, and a different choice is possible.

This coincides exactly with the biological changes of spring: increased light, higher alertness, appetite for novelty, lower tolerance for the friction of unchanged things. The same neurological shift that makes adults want to repaint walls makes children want to redesign their worlds. The spring clean is not a cultural convention. It is a seasonal biological response.

What the design instinct reveals is what the child actually cares about. The bedroom rearrangement tells you about her preferences for space and order. The LEGO city tells you about his principles of infrastructure. The garden zones tell you about her need for different environments for different activities. These are not trivial. They are documents of interior life, written in furniture and Lego and soil. The plans they draw and don't execute are as important as the rooms they rearrange. Both are information.
