A child is sitting on the floor, entirely absorbed in arranging a collection of small animals into what appears to be a very important meeting. A parent is nearby, perhaps reading, folding washing or attempting to drink a cup of tea before it goes cold for the third time. Nobody is entertaining the child. Nobody is asking questions about the meeting’s agenda. Yet the child is not lonely. They are immersed in a private world while feeling quietly secure in the knowledge that someone dependable is close.
It is an ordinary scene, but the British paediatrician and psychoanalyst Donald Winnicott believed something profound was happening within it. In his influential 1958 paper, The Capacity to Be Alone, he described the ability to be alone as one of the most important signs of emotional maturity. Crucially, he did not believe that this capacity began in isolation. He argued that it developed through the paradoxical childhood experience of being alone while a trusted person was present.
The child plays independently because they do not need to keep checking whether the relationship is safe. The adult’s presence has become a kind of emotional background music: reassuring but not intrusive. Over time, that sense of security may be carried within the child, allowing them to spend time alone without feeling abandoned, invisible or incomplete.

Winnicott’s language belongs to a different era, and some of his wider psychoanalytic ideas remain debated. But this particular insight still feels strikingly relevant. Perhaps the ability to enjoy one’s own company is not evidence that a person needs less love. Perhaps it is one of the things that secure love makes possible.
Being alone is not the same as being lonely
Modern life often treats all forms of aloneness as though they are versions of the same problem. A child playing alone in the playground may worry adults. A teenager who closes their bedroom door is assumed to be withdrawing. An adult who goes to a film or café alone can attract the sort of sympathetic glance usually reserved for someone whose birthday party has been forgotten.
But solitude and loneliness are not interchangeable. Loneliness is the painful feeling that our need for connection is not being met. Solitude simply describes time spent apart from other people. It can feel peaceful, restorative and freeing, or uncomfortable, empty and imposed. Much depends on whether it is chosen, whether we feel secure and whether meaningful relationships remain available to us.
Recent research supports this more nuanced view. Studies of everyday solitude suggest that time alone can lower the intensity of highly aroused emotions, including both excitement and anxiety, creating room for calm and emotional regulation. Research also indicates that autonomy matters: people generally experience solitude more positively when it feels chosen rather than forced upon them. Other work has found no simple relationship between introversion and enjoying solitude, which is a useful reminder that this is not merely an “introvert thing.” Our comfort with being alone can change from one day or stage of life to another.
This does not mean that solitude is automatically healthy, or that loneliness should be romanticised as an opportunity for personal growth. Humans need connection, and prolonged unwanted isolation can be deeply painful. The more helpful question is not whether being alone is good or bad. It is whether a person can move between connection and solitude without feeling that either one threatens their sense of self.
Children learn solitude in the presence of safety
Winnicott’s central idea was surprisingly tender. He suggested that the capacity to be alone grows out of dependable connection. Before a child can feel secure when nobody is there, they need repeated experiences of being themselves while someone trustworthy is there.
This may happen when a toddler becomes absorbed in blocks while a parent sits nearby, or when an older child draws at the kitchen table without needing the adult to admire every line. The parent is available but not directing. The child does not have to perform, entertain or respond. They are free to follow a thought that belongs entirely to them.
This kind of quiet independence can be difficult to protect in a culture that encourages adults to optimise almost every minute of childhood. Parents are offered a vast menu of classes, enrichment activities and educational games, along with the uneasy suspicion that any unstructured hour may be an opportunity permanently squandered. Even play can become something adults supervise with the intensity of a small corporate merger.
Yet a child who is constantly entertained has fewer chances to discover what emerges when nothing has been arranged for them. Boredom may initially produce complaints, dramatic sighs and declarations that there is “literally nothing to do,” despite a bedroom containing enough objects to stock a modest toy shop. But beyond that first discomfort lies the possibility of invention. A child may build, imagine, draw, wander, read, daydream or simply notice what interests them when no one else is supplying the agenda.
The adult does not need to disappear for this to happen. In fact, Winnicott’s point was that independence develops most securely when it is not confused with abandonment. The parent can remain emotionally available while resisting the urge to enter every game, solve every quiet moment or turn each interest into a teachable activity.
Constant responsiveness can make the self harder to hear
The need to exist through other people does not always look like dependency. It can look like helpfulness, popularity, busyness or exceptional attentiveness to everyone else’s emotional weather. A person may become highly skilled at reading a room, meeting expectations and anticipating what others need, while remaining unsure what they want when nobody is asking anything of them.
Children naturally adapt to the relationships around them. Some may learn that approval arrives when they are cheerful, accomplished, compliant or useful. These are not necessarily messages that anyone consciously gives them. They can emerge subtly, through which behaviours receive attention and which parts of the child seem to make adults uncomfortable.
Over time, a child may become so practised at responding that they rarely experience themselves outside another person’s reaction. Am I being good? Am I making you proud? Are you pleased with me? Do you still need me? The questions may change with age, but the underlying uncertainty remains: Who am I when nobody is watching?
This is one reason solitude can feel surprisingly uncomfortable for adults who appear socially confident. When external feedback falls silent, there may be no familiar signal telling them how to feel or who to be. The phone comes out almost automatically. A message is sent, a podcast begins, a feed is refreshed. Within seconds, other people’s voices fill the space again.
Technology did not create this vulnerability, but it has become remarkably efficient at ensuring we never have to encounter it. A person can now avoid being psychologically alone even while physically isolated. We can carry hundreds of opinions into the bathroom, watch strangers reorganise their kitchens while eating breakfast and discover what a former colleague’s cousin thinks about a news story before we have worked out what we think ourselves.
Healthy solitude is not a rejection of love
The capacity to be alone can be misunderstood as self-sufficiency taken to an extreme: the emotionally mature person who never needs reassurance, help or company. That is not what Winnicott was describing. His theory began with relationship, not independence. The person who can be alone has not eliminated the need for others; they have developed enough inner security to remain themselves when others are absent.
In practice, this may make intimacy easier rather than less important. When people are terrified of being alone, relationships can become burdened with the impossible task of continually proving that they matter. Disagreement feels like abandonment. A delayed reply feels like rejection. Another person’s need for privacy feels like a verdict on the relationship.
Someone who can tolerate solitude may be better able to let others have separate thoughts, friendships and interests. They can miss a person without ceasing to exist. They can love someone without requiring that person to fill every silence. Connection becomes something freely shared rather than constantly used to hold the self together.
The same principle has implications for parenting. Loving children does not require occupying every corner of their inner world. As they grow, they need privacy, secrets, daydreams and interests that do not belong to the family as a whole. A teenager’s closed door can still be frustrating, especially when there is washing on the other side of it that appears to be developing its own ecosystem. But separateness is not necessarily disconnection. Sometimes it is the ordinary work of becoming a person.
The goal is movement, not perfect independence
No one feels comfortable alone all the time. Illness, grief, rejection and major life changes can make solitude feel very different from one week to the next. A child who usually plays independently may suddenly need more closeness. An adult who once treasured an empty house may find it painfully quiet after a relationship ends or children leave home. Emotional maturity is not measured by how little reassurance a person needs.
A healthier capacity may be the ability to move: towards others when connection is needed and back towards oneself when space is needed. It allows closeness without disappearance and independence without emotional exile.
For parents, this may begin with allowing small pockets of undirected time while remaining reliably available. It may mean pausing before rescuing a child from every moment of boredom, or letting an older child pursue an interest that the adults neither share nor entirely understand. It may also involve modelling solitude ourselves: reading, walking, gardening, making something or sitting quietly without treating the moment as wasted.
Children learn from seeing that an adult can be content without being constantly productive, entertained or admired. They also learn that love does not vanish when two people are doing different things.
Perhaps that is the quiet gift hidden inside Winnicott’s idea. The child absorbed in play while a trusted adult sits nearby is learning more than independence. They are discovering that they can wander into their own imagination and still remain connected; that they can have a private self without losing love.
And one day, when the room is empty and no reassuring figure is physically present, they may still carry that security with them. They will be alone, but not abandoned; connected, but not consumed. They will know that other people matter enormously—and that, even in the silence, they continue to exist.
