You’ve probably heard it before: “30% is Good Enough.” Because it’s one of our most often shared statements from the Circle of Security Parenting program. And it brings a breath of relief to many tired, wondering, second-guessing parents.
But here’s the thing:
We made it up (sort of). It was never really about the number.
Where Did the 30% Come From?
The idea that “30% is Good Enough” was first introduced by the co-originators of Circle of Security Parenting in response to a common concern raised by some caregivers who worried that they could not give their child enough.
Drawing on the work of developmental researcher Dr. Ed Tronick, we offered this message to normalize the imperfect, everyday reality of parenting.
Tronick’s research showed that in “low risk” caregiver-infant pairs, caregivers are only accurately in sync with their baby’s signals about 30% of the time. The rest of the time, they were out-of-sync, mismatched in their emotional state.
That means that most of the time, we miss.
We misread cues.
We guess wrong.
We’re distracted, overwhelmed, unsure.
And yet, most babies still go on to develop secure attachment.
Because the most important piece for the baby isn’t about a perfect parent.
It is about the parent’s commitment to stay with them until they get it right. To notice that they’ve missed the mark, to come back, and to repair. In those moments of misattunement, parents are still trying. We stop, take a breath, reflect and get our Hands back on the Circle.
Oh, and by the way, it was Winnicott, a British pediatrician and psychoanalyst who first wrote about the “Good Enough mother.”
The Real Message
The comfort in the “30%” idea isn’t in the number itself.
It’s in the message behind it: You don’t have to be perfect.
You’ll miss things.
You’ll lose patience.
You’ll juggle more than feels possible.
But what matters is that you notice when you’ve missed,
That you come back.
That you keep trying.
This is what builds trust and security — not perfect parenting, but Good Enough.
