Ask a child about something they truly love and you can often see the change immediately.
The child who gave you one-word answers about their day suddenly has plenty to say about rugby. The dinosaur expert corrects your pronunciation of Parasaurolophus. The young dancer demonstrates a step for the tenth time. A child fascinated by animals wants to know why a cheetah can run so fast, while another can explain every detail of their favourite football team.
To adults, some childhood interests can look like passing phases.
Developmentally, that does not make them unimportant.
Research in psychology and education has repeatedly shown that interest is closely connected to attention, motivation, engagement and learning. Interest is not simply something a child either has or does not have; it can develop and deepen when children have opportunities to explore a subject, gain knowledge about it and return to it over time.
But there is another reason children's interests matter — one that has less to do with what they learn and more to do with how they experience their relationship with us.
Taking their interests seriously tells them something important
Children are gradually developing a sense of themselves: what they enjoy, what they are good at, what matters to them and where they fit in the world.
One well-established body of developmental research looks at autonomy-supportive parenting. Despite the name, this does not mean allowing children to do whatever they want. It means listening to their perspective, allowing appropriate choice and initiative, recognising their feelings and interests, while still providing clear parental guidance and boundaries.
Studies following children over time have linked this kind of parenting with stronger self-regulation, feelings of competence, school adjustment and academic outcomes. In one longitudinal study, autonomy-supportive parenting measured when children were five predicted aspects of their social and academic adjustment three years later.
Taking an interest in what fascinates your child is one simple way of putting that principle into everyday life.
It says:
I notice what matters to you.
And, perhaps even more importantly:
I want to understand your world.
Their interests give you something to talk about
Connection with children is not always built through serious heart-to-heart conversations.
Very often, it starts somewhere much more ordinary.
“Why do you think the Springboks did that?”
“Which animal would you most like to see in the Kruger?”
“What makes a racing car faster?”
“If you could visit anywhere in the world, where would you go?”
When adults ask genuine questions, listen to the answers and let children contribute what they know, a favourite interest becomes common ground.
Research into parent-child conversations has shown that talking together — particularly when adults encourage children to explain, remember, describe and discuss thoughts and feelings — plays an important role in children's developing understanding of themselves and their emotions.
The important word here is conversation.
A parent does not need to become an expert on rugby, ballet, dinosaurs or Minecraft. In fact, letting your child teach you something can be remarkably powerful.
Interest also creates a natural doorway into learning
Children tend to engage more deeply with information when they are already interested in the subject. Interest directs attention and encourages children to return to a topic, ask questions and build increasingly detailed knowledge about it.
That means a rugby obsession can lead surprisingly easily into physics, maths, geography, history and human biology.
Animals can lead to ecology and conservation.
Racing can lead to engineering.
Ballet can lead to anatomy, music and culture.
Travel can introduce geography, languages and different ways of life.
The point is not to turn every hobby into a school lesson.
That can achieve exactly the opposite of what we want.
Instead, parents can simply place interesting information within reach and follow the child's curiosity.
Bedtime can be a particularly useful opportunity
Families are busy. Between school, homework, sport, meals, screens, lifts and everything else that fills a normal South African household, there are not always many quiet moments in a day.
Bedtime can provide one.
There is good evidence supporting regular bedtime routines and language-rich activities such as reading and storytelling. Research has associated these routines with aspects of children's sleep and development, while shared reading has a substantial evidence base for supporting language and communication.
And we have evidence from South Africa itself.
In a randomised controlled trial in Khayelitsha, caregivers of 14- to 16-month-old children were trained in dialogic book-sharing — an interactive approach in which the adult and child talk about and explore a book together rather than the adult simply reading at the child. The children showed greater gains in language and sustained attention than children in the control group.
That distinction matters.
The developmental value is not simply in having a book.
It is in what happens between the adult and the child around the book.
Bedtime does not need to become another structured activity. Nor is there convincing evidence that children enter some special psychological state just before sleep in which they suddenly become more emotionally receptive.
It is valuable for a much simpler reason: for many families, it is one of the day's naturally quieter, repeated opportunities to be together.
A few minutes of genuine attention can be enough.
So what does supporting an interest actually look like?
It does not require expensive lessons, elaborate activities or filling every afternoon with extracurricular commitments.
It can be very ordinary:
-
Ask questions about what your child loves — and listen properly to the answer.
-
Let them teach you something you don't know.
-
Find books, documentaries, places or experiences that help them explore further.
-
Connect their interest naturally to the wider world when an opportunity arises.
-
Resist the temptation to turn their passion into achievement. They do not have to be the best at something for it to be valuable.
-
Make room for interests to change. A fascination that lasts six months can still have mattered enormously during those six months.
Supporting a child's interest is not about producing a future professional rugby player, scientist, ballerina or musician.
It is about recognising that the things children care about are part of the way they explore both the world and themselves.
Sometimes the subject matters less than the connection
At Jo's Dreamland, this idea has shaped much of what we create.
Our themed bedding starts with the things children genuinely love. And with many of our collections, our Snuggle & Learn booklets offer facts, questions and activities parents and children can use to explore that interest together.
Not because we believe bedtime needs another curriculum.
Quite the opposite.
We want to give families an easy starting point for the kinds of conversations that might otherwise never happen.
A question about a rugby rule might become a discussion about perseverance.
An animal fact might lead to a conversation about protecting the environment.
A story about travel might prompt your child to tell you somewhere they dream of going.
And sometimes the conversation will go somewhere completely unexpected.
That may be the most valuable part.
Because when we take an interest in what our children love, we are doing more than encouraging curiosity. We are showing them that their ideas, passions and world are worth our attention.
And that is a message worth hearing again and again.
