There’s a particular kind of social calculus that children perform, usually around age ten or eleven, when they start to feel the competing gravitational pulls of their parents and their peers. They want both. They need both. And most of the time, the two coexist without too much friction. But when a mother decides she doesn’t like someone her child has chosen as a best friend, something quietly destructive begins.
A two-year longitudinal study tracking nearly 400 schoolchildren in Lithuania has now measured, with more rigour than anyone previously managed, just how destructive maternal disapproval turns out to be. The short version: forbidden friends very often become former friends. Roughly a third of stable best friendships collapsed over the course of the study, and maternal disapproval was among the clearest predictors of which ones didn’t survive. The findings appear in Child Development.
“Maternal interference in peer relationships can be quite successful,” says Brett Laursen, a developmental psychologist at Florida Atlantic University and senior author of the study. “Moms are very effective relationship ‘hitmen.’ Most friendships don’t survive condemnation by mothers.”
The Mechanism Behind the Damage
Laursen and his colleagues, led by Goda Kaniušonytė at Mykolas Romeris University in Vilnius, followed 394 students aged 9 to 14 through three survey waves across consecutive academic years. They focused on stable, reciprocated best friendships, the kind where both children independently nominate each other. These weren’t casual acquaintances. They were, by every reasonable measure, genuine close friendships.
What the researchers found when they traced the pathways through their data was something more subtle than a simple ban-and-comply story. Yes, some friendships ended because mothers intervened directly, and children more or less went along with it. “Perhaps youth are persuaded by parental arguments,” says Kaniušonytė. “Or want to keep parents happy. Or perhaps the friendship is suffocated by parental restrictions.”
But there was also a second, slower mechanism at work. When a mother expressed disapproval of her child’s friend, something began to corrode inside the friendship itself. Not in the child’s own perception of the relationship, oddly enough. But in the friend’s. The data showed that maternal disapproval predicted a decline in how supported the other child felt within the friendship, and that declining sense of support, in turn, predicted dissolution months later.
Think about what this means in practice. A ten-year-old whose mother disapproves of their best friend starts, perhaps without fully realising it, to pull back slightly. Fewer invitations. A certain guardedness. The friend picks up on this shift. The warmth drains away slowly, incrementally, until there isn’t quite enough left to hold the relationship together. “Mothers successfully disrupt censured friendships by degrading the interpersonal environment until it can no longer sustain the relationship,” as Laursen puts it.
A Victory That Isn’t
There’s an age effect in here that’s worth unpacking. In primary school (the 9 to 10-year-olds), maternal disapproval hit support perceptions harder and faster. Younger children are more porous to parental influence, more likely to bring that friction home into the friendship. By middle school, the direct impact on perceived support was slightly weaker, but low support became a stronger predictor of eventual dissolution. The machinery is the same; the timing just shifts. Which means that even if an older child is better at compartmentalising parental disapproval, the friendship is in more trouble once support levels start dropping.
The researchers are at pains to note that this is not a how-to guide. A dissolved friendship is not, Laursen argues, any kind of parenting victory. “Breaking up a friendship is easy. Helping your child find a suitable replacement is hard, sometimes impossible.” And the child who loses their best friend doesn’t necessarily find a better one. In some cases, particularly among children who were already somewhat socially isolated, the loss leaves them more vulnerable, not less. Friendless children face elevated risk of bullying. Those with just one or two friends are especially susceptible to peer influence, precisely because they have fewer social options and can’t afford to lose anyone.
There’s a grimly ironic circularity to this. A parent disapproves of a friend because that friend seems like a bad influence. The disapproval ends the friendship. The child, now friendless or nearly so, turns to a limited pool of new companions, which may include peers more objectionable than the original. Previous research from the same group links parental prohibition to rising conduct problems and greater involvement with antisocial peers over time.
“Disapproval can be an effective way to disrupt unwanted friendships, but short-term gains come with long-term costs,” says Laursen. “Intervening in peer relationships can create conflict that damages the parent-child bond. Instead of heavy-handed approaches, parents may be better served by fostering warmth and support at home.”
What Parents Actually Control
There’s a developmental window implicit in all of this. At 9 or 10, parents still substantially control the logistics of friendship: who comes over, where children go, how often they meet. By 13 or 14, that control is eroding fast, and the available tools shift from outright prohibition toward subtler influence, sharing opinions, planting doubts, asking pointed questions.
It’s worth noting that the study measured maternal disapproval as children perceived it, not as mothers reported it. A mother who goes slightly cool when a friend’s name comes up, or asks pointed questions, may not think of herself as expressing disapproval at all. The communication can be remarkably indirect. And yet, the data suggest, the friendship begins to die anyway. Some parents would call that a success. Laursen doesn’t. A child who loses their best friend, and has to rebuild from a shallow social pool, is a child at risk. The friendship was the target; the child’s wellbeing was the collateral damage.
Frequently Asked Questions
How exactly does maternal disapproval cause a friendship to break down?
The research found two pathways. In the first, children comply directly, pulling back from the friendship or having contact restricted until it withers. In the second, subtler pathway, disapproval gradually erodes how supported the friend feels, possibly because the child unconsciously withdraws or because the friend feels unwelcome. This declining sense of support then predicts dissolution months later.
Does it matter how old the child is?
Age shifts the mechanism somewhat. In primary school, disapproval has a stronger direct impact on the friend’s perceptions of support. In middle school, that immediate effect is weaker, but friendships with low support are more likely to collapse because older children rely more heavily on friends for emotional sustenance. Either way, disapproved friendships are at elevated risk across the full age range studied.
Why didn’t the child’s own view of the friendship change?
One of the more striking findings is that maternal disapproval didn’t significantly alter how the child themselves rated the friendship. The child may continue to feel warmly about their friend even as the friend starts to feel less supported. It’s the friend’s perception that deteriorates first, suggesting the child is often the last to realise the relationship is in trouble.
What should parents do instead of expressing disapproval?
The researchers suggest that warmth and support within the parent-child relationship are more effective buffers against unwanted peer influence than direct prohibition. A securely connected child is better positioned to navigate peer pressure, and a parent who forbids a friendship risks damaging both the friendship and their own relationship with the child. Prior research consistently links parental prohibition to increased defiance and deeper involvement with antisocial peers over time.
Could these findings apply to fathers as well?
The study focused on mothers, who tend to be the primary managers of young children’s social lives in the age groups studied. Whether paternal disapproval operates through the same mechanisms remains an open question, though it would be surprising if fathers had no comparable effect.
