A third culture kid is a child who spends a significant part of their early years outside their parents' home culture, building a sense of self from several places at once. At preschool age, identity is concrete: it lives in family routines, food, language, the people a child loves and the places that feel safe. Children aged two to six do not yet think in nationalities, so what helps most is stable rituals, warm relationships, a respected home language and honest, simple preparation for every move.
Many expat and mixed-nationality families in Ho Chi Minh City are raising children who were born in one country, have parents from two others and are now learning Vietnamese and English at preschool. Relatives may ask where the child will feel at home. This guide explains what the third culture kid idea means, what research and experience suggest about identity in early childhood, how to handle being visibly foreign in a Vietnamese setting, how to prepare a small child for moves and goodbyes, and what happens to a language a child stops using.
Where the idea comes from
The term third culture kid was coined by the American sociologist Ruth Hill Useem, who studied American families living in India in the 1950s. She used the phrase third culture to describe the shared way of life that develops among people living between cultures, distinct from both the home culture and the host culture. Children raised in that space were the third culture kids.
The idea reached a wide audience through the book Third Culture Kids: Growing Up Among Worlds by David C. Pollock and Ruth E. Van Reken, first published in 1999 and updated in later editions. Pollock and Van Reken described a recurring pattern: children who move between countries often develop strong cross-cultural skills and a broad view of the world, along with a feeling of rootlessness, repeated grief over lost places and friends, and difficulty answering the question of where they are from. Van Reken later proposed the wider term cross-cultural kids to include children of mixed-heritage families, minority children and others who grow up across cultural boundaries without necessarily moving countries.
Most of the TCK literature is based on older children, teenagers and adults looking back. Very young children experience the same moves and mixtures, but in a different way. A three-year-old does not wonder whether they are more Swedish or more Vietnamese. They notice that breakfast is different on weekends with their father, that the teacher says a word their mother does not know, and that their best friend has gone away. Understanding this difference helps parents focus on what matters at this age.
How identity forms between two and six
Preschoolers build their sense of self from concrete experiences. Developmental psychologists describe young children's self-concept in terms of what they can do, what they own, who they belong to and what they like. A four-year-old might describe themselves as someone who has a little sister, likes dinosaurs and eats rice porridge at school. Nationality and ethnicity are abstract categories that children only begin to understand in later childhood.
That does not mean young children are blind to differences. Studies have shown that infants and toddlers are sensitive to language and accent. Katherine Kinzler, Emmanuel Dupoux and Elizabeth Spelke reported in 2007 that infants preferred to look at speakers of their native language and that young children chose native-accented speakers as friends more often than foreign-accented ones. Children also notice differences in appearance by preschool age and may comment on them out loud, sometimes awkwardly.
For a third culture child, this means identity in the preschool years is mostly about belonging: knowing that their family is a safe base, that their languages are welcome, and that they fit in with the children around them. Parents can support that by keeping family rituals steady through changes, talking openly and positively about the different places and people in the child's life, and giving simple, honest answers when the child asks why things are different.
Common strengths and challenges
Pollock and Van Reken, along with many later writers on international families, describe a mix of gifts and difficulties for children growing up between cultures. The table adapts these to the preschool years. Every child is different, so treat it as a list of things to watch for, not predictions.
| Area | Possible strength | Possible challenge | What parents can do |
|---|---|---|---|
| Languages | Early ear for several languages | The weakest language fades after a move | Protect home-language routines and speakers |
| Relationships | Comfort with people from many backgrounds | Repeated loss of friends and carers | Mark goodbyes, keep some contact going |
| Adaptability | Learns new routines quickly | Constant adapting can be tiring | Keep a few rituals the same everywhere |
| Sense of place | Many places feel familiar | No single place feels like home | Tell family stories about each place |
| Being visible | Learns early to handle attention | Stands out in local settings | Prepare simple responses and stay calm |
The last column matters most. Most of the challenges are not caused by moving itself but by moves that happen without preparation, explanation or a chance to say goodbye. Parents cannot remove the losses that come with an international life, but they can make sure the child is not facing them alone.
Being visibly foreign in a Vietnamese setting
Children from many expat families stand out in Saigon, especially outside the most international neighbourhoods. Strangers may comment on a child's hair or skin, touch their cheeks, ask to take a photo or call out a friendly word about foreigners. In most cases this is warmth and curiosity rather than rudeness. Affectionate attention to small children, including other people's children, is common in Vietnam. Still, it can be overwhelming for a shy toddler.
Preparing the child helps. Explain in simple words that people in Vietnam often love small children and like to say hello. Give your child permission to say no to touching, and model a polite response yourself, such as smiling, waving and gently moving on. Children follow their parents' tone: a calm, friendly response teaches them that the attention is harmless, while a tense reaction teaches them it is threatening.
In class, being one of a few children from another background can work in both directions. Classmates may be curious about a child's language or food, which can be a source of pride. Occasionally a child may feel left out or be singled out. Ask the teacher how they handle differences in the group, and let them know if your child has mentioned anything that upset them. Children's picture books that show families from many backgrounds can also help, both at home and in class.
Preparing a preschooler for a move
Many international families move every few years. David Pollock's RAFT model, widely used in international schools, suggests four elements for a healthy departure: reconciliation, affirmation, farewells and thinking ahead to the destination. For small children it can be translated into simple steps.
- Tell the child early enough to adjust, but not so early that it becomes an abstract worry. For preschoolers, a few weeks is usually enough, with more concrete detail closer to the date.
- Explain with simple facts: where you are going, who is coming, what stays the same, such as family routines and favourite toys.
- Make space for feelings. Name sadness, worry and excitement, and let the child know all of them are fine.
- Plan proper goodbyes with friends, teachers, helpers and favourite places. A small party, a photo album or a drawing exchange gives the ending a shape.
- Pack a familiar bag the child helps choose, with comfort objects, a favourite book and something from the place you are leaving.
- Show the destination before you arrive, with photos of the new home, school or nearby park, and talk about what the child might enjoy there.
- After arriving, restore familiar routines quickly, especially meals, bedtime and the home language.
Young children may show stress after a move through sleep changes, clinginess, tantrums or a temporary step back in skills such as toilet training. This usually settles within weeks as routines return. If it does not, talk to a pediatrician or a child mental health professional familiar with international families.
What happens to a language a child stops using
Families leaving Vietnam often ask what will happen to the Vietnamese their child learned at preschool. The honest answer is that young children can lose a language quickly once they stop hearing it. Research on internationally adopted children illustrates this strongly. Christophe Pallier and colleagues published a study in 2003 of adults who had been adopted from Korea by French families between the ages of three and eight. As adults, they did not recognise Korean better than native French speakers who had never learned it, and their brain responses to Korean looked similar to those of French speakers with no Korean.
Later studies with other adoptees have suggested that some traces may remain and can make relearning easier, but the practical message for families is clear. A language acquired in early childhood needs ongoing use to survive. For a child who learned Vietnamese at preschool and moves to Europe at five, some loss is likely and normal.
If keeping some Vietnamese matters to your family, a few habits can help: video calls with a former teacher, helper or friends, Vietnamese songs and stories at home, contact with Vietnamese-speaking communities in your new country, and visits back. Expect the language to become passive rather than disappear entirely if contact continues. The same principle applies in reverse to a home language that fades during a long stay in Saigon, which is why protecting it during the years here matters.
Building a portable sense of home
Rituals that travel. A Friday pancake breakfast, a particular bedtime song or a family walk on Sunday can be repeated in any city. These routines carry the feeling of home through every move.
Objects with stories. A blanket from a grandmother, a toy bought in a Saigon market, a shell from a beach holiday. Telling the story behind objects helps children connect places and people into one life.
A family map of places. Talk about all the places the child has lived or visited, the people there and what you did. Children who hear their story told as a whole are less likely to feel their life is a series of disconnected breaks.
Respect for every language. When all of a child's languages are welcome, the child does not have to leave part of themselves behind in each place.
Staying in touch, realistically. Young children cannot maintain friendships across continents on their own. A few photos, cards or video calls with key people help, but it is fine if most contacts fade over time.
Room for the host culture. A child who has lived in Saigon carries something of it forward: a taste for certain dishes, a few Vietnamese songs, the memory of a teacher or a festival. Keeping some of that alive after you leave, through food, photos or a lantern brought out each autumn, tells the child that this chapter of their life counts too.
Câu hỏi thường gặp
Is my child a third culture kid if they were born in Vietnam?
Being born in Vietnam does not exclude a child from the third culture experience. What matters is that the child grows up outside the parents' home cultures and builds a sense of self from several places. Ruth Van Reken's wider term cross-cultural kids also includes children from mixed-heritage families and other cross-cultural backgrounds.
At what age do children start asking where they are from?
Many children start asking around school age, when classmates ask them and they begin to understand countries and nationalities. Preschoolers may say they are from the city they live in or from their parents' country without really understanding the difference. Simple, honest answers that name all the places that matter are usually enough.
Should we avoid moving while our child is in preschool?
Families often cannot choose the timing. Young children can adapt well to moves when routines stay stable and goodbyes are handled with care. If you have a choice, avoiding a move at the same time as other big changes, such as a new sibling, can make the transition easier.
How do we answer relatives who say our child has no roots?
You can explain that your child's roots are in the family, its languages and its stories, and that many children today grow up across several places. Showing relatives how much the child knows about them and their country, through calls and visits, is often more convincing than any argument.
Will my child lose their home language if we stay in Saigon for many years?
The risk is real if the home language gets few hours and few speakers while school and city life run in Vietnamese and English. Protecting home-language routines, adding more speakers and visiting the home country regularly greatly improve the chances that your child keeps it.
Is it normal for my child to regress after a move?
Temporary regression, such as more tantrums, clinginess, sleep problems or toilet-training accidents, is common in young children after a big change. It usually settles within weeks as routines return. If it continues or seems severe, talk to a pediatrician or a child mental health professional.
