To every mother reading this, and to every woman who has ever mothered — a daughter, a friend, a stranger, a wounded child not your own — today I want to thank you.

I have spent the last 5 years of my life staring directly into the data on what happens to children when they are not mothered well. The statistics are devastating. They are also why I want to say what I am about to say with as much weight as I can put behind it.

The word mother is most powerful when it is used as a verb. To mother is to see a child for who they truly are and to call them out toward that self. To nurture. To attune. To train a child not in the way you wish they would go, but in the way they were made to go. That is not a small thing. That is the most consequential work a human being can do.

The science of childhood trauma has taught me something I did not learn in thirty years of corporate engineering. A child’s brain is not built by genes alone. It is built by the people who hold it. Every time a mother soothes a crying infant, she is wiring an amygdala that will not fire in panic for the rest of that child’s life. Every time she names what her child is feeling, she is building a prefrontal cortex that will one day be able to regulate emotion under stress. Every time she stays present through a tantrum instead of withdrawing, she is teaching a nervous system that the world is safe.

This is not metaphor. This is neurobiology. The most upstream intervention for every disease, every addiction, every suicide, every act of violence we treat downstream in this country — is a mother who was given the support to mother well.

The work I do at UACT is, in the end, about giving every mother that support. Because most of the mothers I have studied did not fail their children. They were failing themselves long before their children were born, and no one had ever taught them otherwise.

So today, on this day, I want to say a few things plainly.

To the mothers who feel like you are not doing enough — you are doing the most important work in human history. You are wiring the brain of a person who will outlive you. You are healing wounds in your child that no medicine on earth can reach. You may not see the impact today. You will see it in fifty years, when your grown child holds his own child and stays calm in a moment that would have broken him without you.

To the husbands and partners reading this — if you are watching the woman in your life mother a child, you are watching a healer at work. Tell her. Today. Not in a card. Out loud. Tell her you see what she is doing. Tell her it is the most consequential thing happening in your home. She probably does not know.

To the children, the grown children, the men and women whose mothers loved them imperfectly the way all mothers do — call her today. If she is gone, sit with her for a moment in your mind. Whatever you became, she had a hand in. The good parts especially. Even when she didn’t know she was making them.

And to the women who are not mothers but who have mothered — the aunts, the teachers, the foster parents, the chaplains, the older sisters, the friends who showed up when no one else did — you are mothers in the verb. You have healed children who were not yours. There is no higher calling.

Thank you for being who you are. Thank you for the late nights and the patient mornings and the times you said the right thing because you somehow knew, and the times you didn’t and tried again the next day.

Childhood trauma is the largest preventable cause of death in human history. Mothers are the largest preventable answer to it. The world we are trying to build at UACT — a world where every child is healed, every wound is named, every cycle is broken — begins and ends with you.

Today the field of trauma research has a name for what mothers do. We call it co-regulation. We call it secure attachment. We call it the foundation of healing. The science is finally catching up to what mothers have always known.

Happy Mother’s Day. Thank you for the work nobody pays you for. Thank you for the work that makes everything else possible. We see you.
