Psychology says grandparents may treat grandchildren differently from their own children, and it’s not just spoiling

There is a familiar family phenomenon: a parent who was once strict with their own children suddenly becomes remarkably patient with grandchildren. They may tolerate messes they never accepted from their children, buy treats they once banned and spend hours listening to stories they have heard several times. It can leave adult children wondering: “Why didn't I get this version of you?”

Psychology does not establish that grandparents literally love grandchildren more than their children. Instead, research suggests that the grandparent-grandchild relationship has a different emotional structure, shaped by life stage, reduced parenting responsibilities, emotional closeness, family identity and evolutionary investment.

Psychology Says Grandparents Have a Different Role From Parents

Parenting and grandparenting are fundamentally different roles. Parents are generally responsible for everyday decisions involving discipline, education, finances, safety and long-term development. Grandparents often interact with children without carrying the same level of daily responsibility. That difference can change how affection is expressed.


Research on grandparental investment by David A. Coall and Ralph Hertwig describes grandparental involvement through evolutionary, social and economic perspectives. Their work emphasizes that grandparents can provide resources and support while operating within a very different family role from parents.

A grandparent may therefore be able to concentrate more heavily on companionship, affection and enjoyment, while parents have to think about homework, bedtime and boundaries.

Psychology Says More Time for Affection Can Change the Relationship

The life stage of grandparenthood may also matter. Psychologist Laura L. Carstensen developed Socioemotional Selectivity Theory, which proposes that people's social goals change as they perceive their remaining time differently.

As people age, emotionally meaningful relationships can become increasingly important. Rather than maximizing the number of social connections, older adults may prioritize relationships that provide emotional meaning and satisfaction.

Grandchildren can become part of that emotionally meaningful circle. A grandmother who once spent decades balancing work, parenting and household responsibilities may now have more psychological space to savor small interactions: reading a story, baking together or watching a child play.

Psychology Says Grandparents Can Experience the Joy Without the Same Daily Pressure

Consider two situations. A parent sees a child refusing to eat dinner and thinks about nutrition, routine and discipline.

A grandparent may see the same child and think, “Let them have dessert tonight.” The difference does not necessarily reflect stronger love. It reflects different responsibilities.

Parents are often responsible for preparing children for adulthood. Grandparents can occupy a less disciplinary role, allowing their relationship to contain more play and indulgence.

This distinction can make grandchildren perceive grandparents as unusually warm or relaxed.

Psychology Says Emotional Closeness Can Strengthen the Grandparent Bond

Research consistently finds that emotional closeness is an important feature of grandparent-grandchild relationships.

A systematic review examining adolescent grandchildren found that emotional closeness is influenced by relationship factors, communication, distance, health and relationships between grandparents and parents. The researchers described the bond as involving reciprocal influence, emotional closeness and willingness to maintain the relationship across the lifespan.

Another study of 171 young adults found that affectionate communication from grandparents was associated with greater perceived emotional closeness, shared family identity and social support.

This can help explain why grandchildren sometimes describe grandparents as people they can talk to about things they cannot easily discuss with parents.

Psychology Says Affection Can Become a Two-Way Emotional Reward

Affection Exchange Theory, associated with communication researcher Kory Floyd, proposes that affectionate communication can play an important role in human relationships.

In research involving young adult grandchildren, affection received from grandparents was associated with perceptions of closeness, family identity and social support. The relationship therefore isn't simply about what grandparents give children.

Grandparents can also receive emotional rewards from the relationship.

A grandchild's excitement when seeing them, affection, curiosity and trust can reinforce the grandparent's sense of connection and family continuity.

Psychology Says Evolution May Also Play a Role

Evolutionary psychology offers another explanation through kin selection and inclusive fitness.

Grandparents share genes with their grandchildren, meaning that helping grandchildren can theoretically contribute to the continuation of shared genetic material.

Research on grandparental investment has examined this possibility alongside social and cultural explanations. Coall and Hertwig caution, however, that no single theory explains all grandparental investment.

Interestingly, research has also identified differences in investment depending on family relationships and lineage. A large British cohort study involving more than 7,000 participants found differences between maternal and paternal grandparents in contact and financial support, although such patterns are influenced by many social and family factors.

So biology may contribute to the tendency for grandparents to invest in descendants, but it cannot explain every individual family.

Psychology Says Grandparents May Also See Their Children Through Their Grandchildren

There is another psychological layer: family continuity. A grandchild can represent the continuation of a family across generations. For some grandparents, watching a grandchild develop may bring memories of raising their own children back into consciousness.

But the experience is different because they are now observing another generation. The child may therefore become both an individual they love and a symbolic connection to their own life history. Research has found that close grandparent-grandchild relationships can influence grandchildren's beliefs, values and perceptions of their own lives.

Psychology Says “More Spoiled” Does Not Necessarily Mean “More Loved”

Perhaps the biggest misconception is that grandparents' willingness to spoil grandchildren proves that they love them more. It may instead mean they have different emotional incentives and responsibilities. A parent may say, “No more sweets.”

A grandparent may secretly hand the child another cookie. Both can be expressions of affection. The difference is that the grandparent may not be responsible for dealing with the consequences every evening.

Psychology Says Grandparent Love Is Often a Different Kind of Relationship

The special relationship between grandparents and grandchildren may therefore be less about love being stronger and more about love being expressed differently.

Parents often have to combine affection with responsibility, discipline and preparation for independence. Grandparents may have more freedom to emphasize warmth, storytelling, play, emotional support and shared memories.

Research supports the importance of these intergenerational bonds, with a 2026 meta-analysis of 59 independent samples and more than 71,000 participants finding a small but positive association between grandparent-grandchild relationship strength and grandchildren's developmental outcomes.

So when grandparents seem to adore their grandchildren with almost unreasonable enthusiasm, psychology offers a less dramatic explanation. They may not love their children less.

They may simply have reached a stage of life where love can be experienced with fewer responsibilities, more perspective and more time to enjoy the relationship.

FAQs

Do grandparents really love their grandchildren more than their children?

There is no scientific evidence establishing that grandparents universally love grandchildren more than their own children. Research instead shows that grandparent-grandchild relationships can be emotionally close and operate under different social and family circumstances.

Why are grandparents often more lenient with grandchildren?

Grandparents typically have fewer day-to-day parenting responsibilities than parents. This can allow them to emphasize play, affection and enjoyment rather than discipline and long-term decision-making.
