No one warns you that becoming a parent might crack something open in you. That holding your child, something so soft, so dependent, so utterly in need of protection, might bring things to the surface that you spent years keeping carefully below it.

And yet, for many parents, this is exactly what happens. Parenthood, matrescence, the early postpartum period, these experiences have an uncanny ability to reach back into our histories and pull things forward.

If you’ve found yourself unexpectedly weeping over your childhood, feeling triggered by your baby’s cries, struggling with your own parents in new ways, or experiencing emotional reactions that feel disproportionate to the moment, you are not losing your mind. You may be encountering old trauma for the first time in a long time.

What Is Matrescence?

Matrescence is a term coined by anthropologist Dana Raphael in the 1970s and brought into wider awareness by reproductive psychiatrist Alexandra Sacks. It refers to the developmental transition of becoming a mother, a process as significant and identity-reshaping as adolescence, but almost entirely without cultural acknowledgment.

During matrescence, women often experience a profound shift in identity, a renegotiation of relationships, a confrontation with their own needs and limitations, and a deep, sometimes painful, reckoning with their own history of being mothered.

Why Parenthood Can Activate Old Trauma

There are a few reasons why becoming a parent is such a powerful trauma activator.

The Attachment System Is Fully Online

When you have a baby, your attachment system, the same system that was shaped in your earliest relationships, becomes intensely activated. You are now in an attachment relationship of profound intimacy and dependency. For many people, this lights up old wounds from their own early attachment experiences: the ways they were or weren’t held, responded to, seen.

Your Baby’s Developmental Stages Mirror Your Own

As your child moves through developmental stages, they can unconsciously bring you back to your own experience of those stages. Your baby’s dependency and helplessness can activate memories, conscious or not, of your own helplessness. Their tantrums, their fear, their need for comfort, can all be unexpectedly resonant.

Your Own Parents Are More Present

Whether they’re physically present or not, becoming a parent often brings your own parents back into sharp focus. You may find yourself reckoning with how you were raised in new ways, grieving what you didn’t receive, feeling angry in ways you’d suppressed, or desperately trying not to repeat patterns you saw modeled.

Sleep Deprivation and Depletion Lower Your Defenses

The defenses and coping strategies that kept difficult feelings at bay, keeping busy, being productive, maintaining control, are much harder to sustain when you’re exhausted, physically depleted, and hormonally shifted. Things that were carefully managed can begin to surface.

Signs That Old Trauma May Be Coming Up

  • Feeling triggered by your child’s cries or needs in ways that feel bigger than the moment
  • Sudden grief, anger, or sadness about your own childhood
  • Difficulty being patient with your child in ways that remind you of a parent’s behaviour toward you
  • Feeling unexpectedly disconnected from your baby at times
  • Hypervigilance about your child’s safety that goes beyond typical parental worry
  • Conflict with your own parents intensifying since having a child
  • Feeling like you’re parenting the child you once were

This Is Actually an Opportunity

I know that might be hard to hear when you’re in the thick of it. But parenthood, precisely because it opens us so wide, can be one of the most powerful invitations to heal that we ever receive.

Many parents find that becoming a parent motivates them to seek therapy in ways nothing else ever did, because now it’s not just about them. They want to break cycles. They want to parent differently. They want to give their child what they didn’t have.

That desire, that fierce, loving intention, is itself healing. And with the right support, the work it points toward is very much possible.

You don’t have to have had a perfect childhood to be a good parent. You just have to be willing to do the work of understanding your own story, and that work, done with compassion and support, changes everything.
