How Your Own Attachment Style Shapes the Way You Parent

One of the most striking findings in attachment research is deceptively simple: the best predictor of a child’s attachment style isn’t what happened during the child’s infancy. It’s how the parent understands their own childhood.

This comes from a measure called the Adult Attachment Interview, developed by Mary Main and colleagues in the 1980s. It’s not a questionnaire about parenting philosophy or childhood history. It’s an interview that measures something more elusive: how coherently you can narrate your early experiences. How you talk about your parents — whether your account is contradictory or integrated, idealized or dismissed, still emotionally live or reflectively held — predicts, with remarkable accuracy, how your children will be classified in the Strange Situation procedure.

This finding has been replicated many times, across many cultures. It’s robust and it’s sobering, and it deserves more than a passing mention in most conversations about parenting.

What “Making Sense of Your Childhood” Actually Means

The Adult Attachment Interview classifies adults into categories that roughly parallel the childhood attachment categories. Adults classified as “secure/autonomous” can speak coherently and with appropriate emotional coloring about their childhoods, whether those childhoods were difficult or not. They can acknowledge imperfections in their parents while still holding a nuanced, integrated picture of them as people. They’ve processed the past enough that it informs rather than drives them.

Adults classified as “dismissing” tend to minimize the importance of early relationships. They may idealize their childhoods without being able to provide specific supporting memories, or they may insist that their difficult childhoods had no lasting effect on them. The past is either heavily edited or actively avoided.

Adults classified as “preoccupied” are still, in some sense, living in the past. Their accounts of childhood are often long, confused, and emotionally tangled — they may become angry or sad mid-sentence, lose the thread of what they were saying, or seem to be working something out in real time rather than reflecting from a settled place.

Adults classified as “unresolved/disorganized” show specific lapses in reasoning or monitoring when discussing loss or abuse — their narrative coherence breaks down momentarily around these topics in ways that suggest the experiences haven’t been integrated.

And the finding is that these adult classifications predict children’s attachment styles — before the children are even born, in studies that conduct the Adult Attachment Interview during pregnancy.

The Dismissing Parent

Dismissing adults tend to raise children with avoidant attachment — though of course there are exceptions, and attachment transmission is not destiny.

What this looks like in practice: the dismissing parent is often not cold or unkind. They may genuinely love their child and work hard to provide for them. But they tend to be uncomfortable with emotional expression, their own and their child’s. When the child falls and cries, the dismissing parent’s instinct may be to help them calm down and move on rather than to dwell in the distress. When the child is afraid, the response may be matter-of-fact reassurance rather than empathic attunement. The message the child receives, repeatedly and without anyone necessarily intending it, is that big feelings are better suppressed.

The child’s nervous system learns this lesson. By twelve to eighteen months, many children of dismissing parents have already developed a behavioral strategy: they downregulate their attachment behavior in the presence of the caregiver. They appear relatively unaffected by separation and reunion in the Strange Situation, not because they aren’t distressed, but because physiological measures show elevated cortisol even when their behavior looks calm. They’ve learned to hide their need.

Parents with a dismissing style are often parenting exactly as they were parented. The emotional inaccessibility they experienced as children has become their own way of being in the world, including their default relationship to their children’s emotions. They’re not choosing to be emotionally unavailable — they’ve simply internalized a model of caregiving that treats emotional expression as something to be managed and moved past rather than held.

The Preoccupied Parent

Preoccupied or anxiously attached adults tend to raise children with anxious-ambivalent attachment.

This is a different kind of emotional challenge. Where the dismissing parent doesn’t engage enough with the child’s emotional life, the preoccupied parent often engages too much — but in ways that are more about the parent’s own emotional experience than the child’s. The preoccupied parent may be inconsistently available: intensely focused on the child one moment, then emotionally absorbed in their own preoccupations the next. The child can’t develop a reliable expectation about whether connection is available.

There’s also a subtler dynamic that can emerge: the preoccupied parent may, without realizing it, need the child to regulate their own emotions. The parent’s anxiety may seek soothing in the child’s presence or be activated by the child’s distress in ways that make the parent’s need the prominent emotional fact in the room. The child learns to monitor the parent’s emotional state — to manage the parent’s feelings in order to ensure the parent’s availability. This is a developmental burden that should never fall to a child.

The child who grows up as the emotional caretaker of their parent often becomes an adult who is hypervigilant to others’ emotional states, struggles to identify their own needs, and can’t tolerate the anxiety of not knowing whether a relationship is okay. The anxious attachment style, with its characteristic monitoring and hyperactivation of the attachment system, emerges from precisely this relational environment.

The Unresolved Parent

The most difficult, and the most important to understand, is the unresolved/disorganized parent — an adult who has experienced significant loss or trauma that hasn’t been processed and integrated.

Mary Main’s research showed something painful: parents with unresolved trauma or loss sometimes become frightening to their children, even without any conscious intention to harm them. The parent may become briefly, momentarily frightening when their own trauma is activated — a sudden flash of dissociation, a moment of rage that passes but registers as threatening, a withdrawal that the child can’t make sense of. Or the parent may become frightened in the child’s presence — responding to the child with visible fear or helplessness — which is equally disorganizing to the child.

The child is then in an insoluble dilemma. The person who is supposed to be the safe haven — the person who should resolve fear — is also a source of fear. The attachment system, which drives the child toward the caregiver under threat, collides with the fear system, which drives the child away. There’s no behavioral solution to this dilemma. The result is disorganized attachment — the child who freezes, approaches and retreats, or shows other contradictory behaviors in the presence of the caregiver.

Children with disorganized attachment are at higher risk for a range of difficulties across development, including trauma symptoms, dissociation, and significant relationship problems in adulthood. Disorganized attachment in childhood is closely associated with disorganized or unresolved attachment status in adulthood — which creates the intergenerational transmission this work is partly designed to interrupt.

The Exception: Earned Security

Here is where the research becomes genuinely encouraging.

Adults who experienced difficult, even traumatic childhoods but who have worked to understand and integrate those experiences are classified as “earned secure” on the Adult Attachment Interview. Their attachment classification is secure, not despite their difficult histories, but because they’ve done the reflective work to make sense of those histories.

And earned secure adults — like naturally secure adults — tend to raise securely attached children.

This is one of the most hopeful findings in developmental psychology. It means the cycle can be broken. Not by having had a good enough childhood, but by doing the work to understand the one you had. The question the Adult Attachment Interview is actually asking is not “what happened to you?” but “how do you understand what happened to you?” Those are very different questions.

Why This Isn’t About Blame

If you’ve read this far and feel a wave of shame or worry about how your own attachment history might be shaping your children, I want to say something directly: this research is not an indictment. It’s a map.

Most parents are doing exactly what was done to them, with the best intentions, because parenting the way you were parented is simply the default — it’s what you internalized before you had any capacity for reflection. The parent who minimizes their child’s emotions may be the child who had their emotions minimized. The parent whose anxiety floods the caregiving relationship may have never had a regulated, attuned caregiver to learn from. These are not moral failures. They’re the unsurprising outcomes of early experiences that shaped how people relate to emotional life and connection.

What the research asks of us is not a perfect childhood or a perfect parenting style. It asks for the willingness to look honestly at our own histories and to understand, as clearly as we can, how those histories live in us. That’s the work that changes the pattern. And it’s work that can happen at any point — including long after the early years of your children’s lives.

The single most powerful thing most parents can do for their children’s attachment security isn’t to change their parenting techniques. It’s to understand their own story.
