Four Questions That Help Us Understand Your Child’s Nervous System
When parents bring their child to a pediatric chiropractor, it’s often because they are noticing patterns—how their child moves, reacts, or regulates themselves. They have colic/reflux and are always upset after eating. They might be on the autism spectrum and get dysregulated easily when there are too many people, bright lights or loud noises. The child might have ADHD and be distracted constantly while doing homework but can focus on Pokemon or Minecraft for hours.
One helpful way pediatric chiropractors might think about these patterns comes from biology, using something called Tinbergen’s Four Questions. While originally designed to understand animal behavior, this framework also helps explain how a child’s nervous system functions and develops. It reminds us that behavior and movement aren’t random—they reflect how a child’s brain and body are working together right now.
The first two questions focus on the present and the past. The first question discusses what is know as Mechanism, looking at what’s happening in the nervous system today, such as how a child processes sensory input, coordinates movement, or responds to stress. Ontogeny, the second of Tinbergen’s questions, looks at how those patterns developed over time, including early milestones, birth experiences, or periods of stress. Together, these 2 perspectives help families and practitioners understand a child’s current needs without jumping to labels or diagnoses.
The other two questions help pediatric chiropractors see the purpose and the bigger picture. Function, the 3rd question, asks what a behavior might be trying to accomplish—many challenging behaviors are actually protective or adaptive strategies. The final question, Phylogeny, reminds us that many primitive reflexes and stress responses are deeply rooted in human evolution and early development. When viewed together, these four questions encourage a whole‑child approach—one that sees each child’s nervous system as adaptive, developing, and worthy of support as they grow.
Someone asked me yesterday, “my child has ADHD but might also have autism. How would you approach their case?” Using Tinbergen’s four question concepts, we approach each child not as what their diagnosis is, but how their nerve system is functioning. It is not a ‘cookie-cutter’, one-size-fits-all method, but very individualized based upon what sort of exam findings they have. Then we tailor-make a care plan for each child, and importantly perform re-evaluations every 5-10 visits to make course-corrections as the child improves. If you want a very gentle, individualized approach to help improve your child's nervous system, then pediatric, brain-based chiropractic is for you...and your child!
