Science shows that even after birth, a child’s DNA can remain inside a mother’s body for years, sometimes a lifetime. These fetal cells travel through her blood, settle in her brain and organs, and become part of her. The phenomenon is known as fetal-maternal microchimerism.

Research led by Amy Boddy, associate professor at UC Santa Barbara, has found these cells in a wide range of maternal tissues. She describes it as “a small amount of genetically different cells or DNA in someone’s body.”

Some of these cells even take on new roles. For example, fetal cells that migrate to the mother’s heart can transform into cardiac cells, working alongside her own to help that organ function. It’s a biological connection that quite literally beats on.

Even after a miscarriage, fetal cells remain in the mother’s body. For women who experience pregnancy loss, “it’s not just in their head that they’re forever changed by that pregnancy,” Boddy says. “Those cells may exist and influence their biology.”

With so much we still don’t know about how these cells function, one thing is certain: motherhood leaves a mark that science is only beginning to understand.

Fetal microchimerism and maternal health: A review and evolutionary analysis of cooperation and conflict beyond the womb

Abstract
The presence of fetal cells has been associated with both positive and negative effects on maternal health. These paradoxical effects may be due to the fact that maternal and offspring fitness interests are aligned in certain domains and conflicting in others, which may have led to the evolution of fetal microchimeric phenotypes that can manipulate maternal tissues. We use cooperation and conflict theory to generate testable predictions about domains in which fetal microchimerism may enhance maternal health and those in which it may be detrimental. This framework suggests that fetal cells may function both to contribute to maternal somatic maintenance (e.g. wound healing) and to manipulate maternal physiology to enhance resource transmission to offspring (e.g. enhancing milk production). In this review, we use an evolutionary framework to make testable predictions about the role of fetal microchimerism in lactation, thyroid function, autoimmune disease, cancer and maternal emotional, and psychological health.

It is with profound sadness that the ILCA recognizes the passing of Dr. Ruth A. Lawrence, a giant whose extraordinary dedication and pioneering work fundamentally advanced the field of human lactation and breastfeeding medicine.

Dr. Lawrence was more than a pediatrician and toxicologist; she was a trailblazing advocate for mothers, children, and the value of human milk. For over seven decades, she helped move the science and practice of breastfeeding into mainstream medicine.

Her compassion, intellectual rigor, and tireless advocacy have left an indelible mark on our profession and the health of families worldwide. ILCA is deeply grateful for her transformative contributions. Her impact will be felt for generations to come.

At dawn, the savannah fell silent as a mother elephant gave birth—not to one calf, but two. Elephant twins are so rare that many rangers never see it in a lifetime. The newborns trembled by their mother’s side as she touched them gently with her trunk, claiming them as her own.

Then the herd gathered. One by one, massive shapes formed a living circle around the family, a fortress of protection. From above, it looked ceremonial, as if the elephants themselves understood they were witnessing a miracle.

Despite her exhaustion, the mother nudged her calves to rise. Wobbly legs straightened, small trunks reached outward, and their first steps were greeted by a chorus of trumpets echoing across the plains. It wasn’t just birth—it was a celebration.

For days, the herd cared for them together. Allomothers stood guard, shared the burden, and proved once again that survival for elephants is rooted not only in strength, but in unity and love.

Two rare lives. One herd’s embrace. A reminder that nature still writes the most breathtaking stories.

A brand-new study following more than half a million children just confirmed something powerful:
babies who were breastfed for at least 6 months had a lower risk of developmental delays… things like speech, language, social, and motor skills.

Even more interesting?

Researchers compared siblings raised in the same home. The child who was breastfed longer had fewer developmental delays than the sibling who wasn’t. That means the difference wasn’t just parenting style or environment, breastfeeding itself played a role.

✨ Exclusive breastfeeding showed the strongest impact, but even partial breastfeeding mattered.

✨ This adds to a growing body of evidence showing how human milk does more than feed, it helps wire the brain and support developmental foundations.

Every drop counts.
Every month makes a difference.
