The most comprehensive review of early childhood science ever assembled was published in 2000 by the National Academy of Sciences. The committee that produced it included Megan Gunnar, Ross Thompson, Alicia Lieberman, William Greenough, and a dozen other scientists whose work built the foundation of what we know about how children develop. Their report was called “From Neurons to Neighborhoods.”
Their first recommendation asked the nation to devote resources to fostering curiosity, self-direction, persistence, cooperation, caring, conflict resolution, and the capacity to feel competent and loved.
The recommendation was not controversial. The science behind it was not contested. The committee was unanimous.
And nothing happened. A tree fell in the woods. No one was listening.
Now read the recommendation list above through the FCD lens and see how they map onto the five pillars. Curiosity and self-direction: Play and Exploration. Persistence: Regulation. Cooperation, caring, conflict resolution: Identity and Purpose (and Connection). The capacity to feel competent and loved: Connection. And the resources to make any of it happen: Resources and Demands.
The five pillars map almost perfectly to a recommendation that a committee of the nation’s foremost developmental scientists made unanimously, twenty-six years ago, and yet no one’s put them together out loud in front of parents in a usable form. Why? (We’re as confused as you are.)
In 2012, Andrew Garner and Jack Shonkoff published the AAP policy statement we mentioned in our first post. (The AAP came back to it in 2021—Garner again, with Michael Yogman—restating the case even more forcefully and naming “relational health” as the organizing concept. We’ll come back to that.) They opened it with a line attributed to Frederick Douglass ("It is easier to build strong children than to repair broken men") and then spent eight pages explaining, again, that the system built to serve children was still organized around waiting for damage and reacting to it
They named the mechanism. Toxic stress, unmitigated by stable caregiving relationships, produces biological changes in the developing brain that persist into adulthood. They named the solution. Relational health, the quality of the child’s bonds with the adults in their life, as the primary buffer against the effects of adversity. They called for a fundamental shift in how pediatrics approaches child development: from reactive to proactive, from deficit-focused to relationship-focused.
It was the same argument as “From Neurons to Neighborhoods.” Updated with twelve more years of evidence. Published in the flagship journal of the American Academy of Pediatrics. Endorsed by the institution that represents every pediatrician in the country. Reaffirmed and sharpened in 2021, with the same lead author, naming “relational health” as the goal.
And the system, by and large, went back to business as usual. The researchers went back to researching, and the agencies, which might have taken up the information to implement the findings, didn’t.
Here is the founding fact of FCD. The science has been clear for a generation, but it needs a messenger. The science was clear before our children were born. And the system that was supposed to translate that science into support for families did not do it.
Jack Shonkoff’s Center on the Developing Child at Harvard has been publishing policy briefs on these same themes for over twenty years. The language gets crisper. The evidence gets stronger. The audience nods. And the default orientation of the system remains: wait until something breaks, then react.
This is what we mean when we say the science is not incomplete. Yes, there are gaps and open questions. We track them carefully, and we will share them with you honestly. The core architecture of what children need to develop well has been established for decades. Connection. Regulation. Play. Identity. Resources. The science told us. We did not act.
The system failure is structural. It is not a failure of individuals. The people working inside the systems are, overwhelmingly, doing their best within structures they did not design. A pediatrician who has twelve minutes per well-child visit is not going to deliver a relational-health intervention no matter how many policy statements her professional association publishes. A teacher with a scripted curriculum is not going to foster curiosity and self-direction, no matter what the National Academy of Sciences recommended in 2000.
It will take at least a generation to change any of this.
But your children do not have a generation. Your children are growing up right now, inside the gap between what the science says and what the system provides. Waiting for the system to catch up is itself a form of neglect.
FCD takes the science that has been sitting in policy reports and academic journals for twenty-six years and translates it into a framework that parents and professionals can use today. Not perfectly or comprehensively. (We are two people with a Substack, not a federal agency, after all.) But the science is there, the framework is sound, and waiting another twenty-six years for the system to move is not acceptable. We’re doing this. Join us!
Try This: Your Child’s Five-Pillar Map
The From Neurons to Neighborhoods committee recommended fostering: curiosity, self-direction, persistence, cooperation, caring, conflict resolution, and the capacity to feel competent and loved.
Map your child against those seven words. Not as a scorecard, but as a snapshot. For each one, ask: Is my child’s current environment giving them room to develop this? Where is the environment supporting it? Where might it be constraining it?
This is not about your child’s performance. It’s about whether the conditions around them are giving these capacities room to grow.
If the answer is “not really” for one of them, that’s useful information. It tells you where to look next.
Consider This: What Are You Waiting for the System to Provide?
The post argues that waiting for the system to translate the science is itself a form of neglect. That’s a strong claim, and it’s directed at institutions, not at you.
But it raises a personal question: Is there something you’ve been waiting for a school, a pediatrician, a therapist, or a program to provide for your child that you could start building yourself? Not because you should have to, but because your child is growing up right now, inside the gap.
