We have all witnessed it: a child "snaps" over something that seems inconsequential, like a crayon being taken away. To the untrained eye, it looks like a sudden, disproportionate reaction. But in reality, the behaviour rarely comes out of nowhere.
Instead, we are seeing the final result of a "Trigger Layer Cake"—a buildup of hidden factors that cause a child’s "emotional bucket" to finally overflow.
Understanding the Layers
When we view behaviour as communication, we stop looking at the event and start looking at the history behind it. The "cake" is made up of layers that stack on top of each other throughout the day:
-
The Biological Layer: This involves anything internal. Is the child hungry because they skipped breakfast? Are they teething, or perhaps fighting off a cold that makes them feel lethargic and uncomfortable? These physiological stressors significantly reduce a child’s threshold for frustration.
-
The Environmental Layer: This covers the external stressors. Is the room too noisy? Does the space feel overcrowded? Has a sudden staff change disrupted their sense of security or routine? These factors create a background hum of stress that a young child may not have the language to express.
The Anatomy of an "Explosion"
Imagine a child’s morning:
-
9:00 AM: The child arrives at the setting having had a poor breakfast (Biological Layer).
-
10:00 AM: The play area becomes increasingly noisy and chaotic (Environmental Layer).
-
10:30 AM: A transition is rushed by staff, creating a sense of urgency and lack of control.
-
11:00 AM: A peer takes their crayon.
The child bites.
To an observer, it looks like a reaction to the crayon. But in truth, that bite was simply the final drop in a bucket that had been filling up for hours. The crayon was merely the catalyst for an already overwhelmed system.
From Reaction to Regulation
Our role as leaders and practitioners isn't just to manage the explosion after it happens; it is to help children regulate their needs before the bucket spills over.
Crucially, we must remember that we cannot reason with a dysregulated child. By the time the "explosion" occurs, the goal must shift entirely to safety and co-regulation. The real pedagogical work, however, happens earlier: identifying these small, cumulative stresses so we can intervene before a child reaches their breaking point.
Proactive Support for Your Setting
In my "Behaviour as Communication" training, we break down these layers for every age group—from the sensory-driven needs of the baby room to the complex social testing of pre-schoolers. We provide your team with the observational tools they need to spot the signs early and offer the right support at the right time.
If you are ready to help your team move away from reacting to "explosions" and towards proactively supporting emotional regulation, let’s start a conversation.

Do you find that your team currently has the time and space to observe these "hidden layers," or does the daily pace of the nursery make this proactive approach feel like a challenge?
