A new study has uncovered something many families may have already sensed: grandmothers often form deeper emotional connections with their grandchildren than with their own children.
It’s a phenomenon rooted not only in love but also in science, psychology, and evolution.

👵💗 The Grandmother Effect: More Than Just Spoiling the Kids
Researchers at Emory University scanned the brains of 50 grandmothers while they viewed photos of their grandchildren, adult children, and unrelated children. The results were surprising—grandmas showed stronger emotional and empathetic responses to their grandchildren than to their own children.
According to the study, viewing images of their grandchildren activated brain areas associated with empathy, emotional processing, and reward far more than photos of their adult kids.

🧠 What’s Happening in a Grandma’s Brain?
Neurologically speaking, grandmothers are wired to feel joy and connection toward the next generation. This aligns with what scientists call the “grandmother hypothesis”—the evolutionary theory that human survival has been enhanced by grandmothers helping raise grandchildren.
“When a grandmother sees a grandchild, her brain literally lights up,” said study lead James Rilling. “It’s a biological reward system in action.”
This means the bond isn’t just emotional—it’s biological.

👶 Why the Grandchild Relationship Feels So Special
There are several reasons why grandmas might feel closer to grandkids:
- Less pressure: With parenting responsibilities passed on to their adult children, grandmothers can focus on love and connection without the daily stress of discipline.
- A second chance: Many grandmothers say they see their grandchildren as an opportunity to experience motherhood again—but with more patience and wisdom.
- Unconditional affection: Grandchildren often provide the kind of spontaneous joy and admiration that’s less common in adult child-parent relationships.
💬 Real Talk: “She’s the Mom I Wish I Had Growing Up”
For many adult children, this closeness can stir mixed emotions. Some express joy at seeing their children so loved, while others feel overlooked—questioning why their mother is more affectionate now than she was in the past.
Psychologists say this may stem from generational growth, personal healing, and changing emotional capacity with age.
🔄 Rewriting the Parenting Story
This study isn’t about competition—it’s about connection. Grandmothers often use their bond with grandchildren to heal old wounds, reflect on parenting choices, and show love in a new, less pressured role.
“I can love freely this time,” said one grandma interviewed for the study. “I’m not as worried about being perfect. I just want to be present.”
🧬 Love That Skips a Generation (But Doesn’t Skip a Beat)
Ultimately, science is confirming what many families already feel: there’s something magical about the grandma-grandchild bond.
Whether it’s baking cookies, sharing stories, or snuggling on the couch, that bond can shape a child’s emotional development in lasting ways.
So, if grandma seems a little extra obsessed with the little ones? Now we know—it’s not just sweet. It’s science.
