Supporting bilingual children who mix languages

Bilingual children often move between English and the languages of home, school and community. A child may use one language for a joke, another for a request and a third for a story. That flexibility is a valuable communication skill, and switching languages is not, by itself, evidence of confusion or a language disorder.

Therapy becomes more useful when the child’s whole language repertoire is respected. Effective strategies for working with bilingual children who mix languages in therapy focus on what the child understands and communicates, which languages support success, and what the family hopes language will do for them in everyday life.

This matters in Australia, where children may hear Vietnamese and Cantonese in Melbourne, Arabic and Kurdish in Sydney, or English and community languages in Queensland. The practical task is to understand the child’s languages without treating one as a problem to be corrected.

Understanding what mixed-language speech can mean

Code switching and code mixing describe moving between languages, sometimes within a sentence. This can be purposeful: children may use a particular language for formulas, affection, authority or humour. A switch can also show that a concept is easier to express in another language. For an adult, it may indicate that the child has not yet learned the English label for an object or action.

Observed pattern	What it may indicate	Helpful response
A whole phrase changes language	The child is selecting familiar or clearer wording	Follow the child and clarify meaning when needed
A single word changes	The concept may be more accessible in another language	Model the phrase in both languages and add a picture or gesture
Grammar from one language appears in another	The child is transferring a familiar structure while learning new words	Accept the meaning, then offer a clear model without demanding immediate correction
Understanding or expression falls in both languages	There may be a broader language difficulty to investigate	Seek comprehensive bilingual assessment and individualised goals

Rather than count switches, look for what happens before and after them. Ask the child to retell a story, show a picture and name what they mean, or repeat a request in the other language. Record comprehension, not only the form of the words. A child who repeatedly replaces a needed English word with a home-language word may need vocabulary support; a child who switches fluidly and responds to both languages may simply be communicating efficiently.

Language differences can also resemble errors. Speakers learning English may transfer sentence patterns, omit endings or use a different word order. Those patterns do not automatically indicate a disorder, and they should not be “corrected” without considering the child’s full language system. Compare performance across both languages, review developmental history and use culturally and linguistically appropriate assessment. A multilingual child can have a genuine language difficulty while still learning two or more languages successfully.

Building a language profile that guides therapy

Start with a language profile, not a list of deficits. Ask which languages the child understands and uses, with whom, and in which settings. Include dialects, signing, reading and writing when relevant. Note whether each language is developing across comprehension, expression, conversation, phonology and literacy, rather than assuming a child has the same level in every domain.

Invite families to contribute without turning them into unpaid interpreters. Parents can model short sentences, record everyday speech and explain the words that matter at home. For formal testing and unfamiliar-language samples, arrange an appropriately qualified independent interpreter. Milestones should be considered across the child’s whole repertoire, not judged with an English-only checklist, and any assessment should use guidance appropriate to the languages involved.

Play gives you another view of comprehension and relationships. If you are choosing tasks for spatial concepts, try play-based preposition activities and adapt the instructions into the languages the child uses. Watch what the child does, not just what they say: pointing to the toy and moving it under the table may show stronger understanding than a verbal answer. Let the family help choose familiar objects so language learning stays connected to daily life.

Setting goals that work across languages

Set goals around communication, rather than eliminating switches. Useful targets include following directions, requesting help, describing an event, repairing a misunderstanding and joining a conversation with peers. The best language for a goal may differ from the strongest language for greetings or stories. For an articulation target, choose the language where that sound affects participation; making the child rehearse it in every language can add unnecessary pressure.

For example, if a child understands two-step directions in Arabic but not yet in English, a goal might be to follow them with visual support in either language while building new English vocabulary. Family and school priorities then guide which language receives extra practice. Record whether the child communicates, responds and learns new words, rather than counting how often they stay in one language.

Shared language between adults also matters. Teachers, childcare staff and speech pathologists should use the same functional goal and agreed cues, even when their everyday wording differs. Bilingual programmes and clinician resources available through Exantema resources can offer additional ways to structure language sampling and goals. Compare them with the child’s goals, and use only tasks that fit the languages and routines you have identified.

Adapting therapy to Australian communities and services

Australian family life brings many language combinations into one home. In Melbourne, families in areas such as Richmond or Box Hill may use Vietnamese, Cantonese, Mandarin and English across generations. In Sydney’s western suburbs, including Punchbowl and Bankstown, Arabic, Kurdish, Assyrian Neo-Aramaic and English may all have a place. These are possibilities, not assumptions about any child: ask about the family’s own languages, dialect and communication preferences.

Perth and regional Western Australia show why telehealth has become a significant part of the local market, connecting families with speech pathologists across distance. In Aboriginal communities, language decisions should involve community members and follow local protocols. In Queensland, some Torres Strait Islander children use English alongside one or more Torres Strait languages, so goals should respect the languages and relationships the family values rather than prioritise English automatically.

Funding shapes access as much as geography. Eligible families may use Medicare-subsidised speech pathology following a general practitioner referral, while an NDIS plan can fund therapy for some children with functional communication needs. Schools employ speech pathologists, and private clinics offer family-selected services. Ask which pathway is paying for each goal and what the child can practise with the people who see them every day.

Plain language and a relaxed Australian conversational style can make sessions welcoming, but familiarity should not replace clarity. Explain what an assessment measures, how interpreters work and what progress looks like. Keep written summaries short, and check whether families prefer formal terms, everyday wording or a mixture of both.

Keeping communication open and making progress visible

Keep progress visible with short, functional updates. A family update can say, “Sam understood a two-step instruction in Vietnamese and asked for help in English after a model.” That is more informative than counting switches or recording only correct English. Share goals with the child, family and relevant school team, and revisit them as the child’s language repertoire and classroom demands change.

When speech pathology works alongside ABA, align the adults on shared cues and functional outcomes. The aim is not to silence one language, but to give the child reliable ways to communicate, make choices and express an idea. If one team insists on English-only responses while another encourages the home language, the child receives conflicting expectations and meaningful attempts may be missed.

Try one of those spatial play activities in your next session, invite the family to share a short home-language sample, and record which language supports the child’s success. Browse the printable materials in the Let’s Talk Speech Therapy shop and choose one resource to adapt for a child’s language profile, so every activity leads towards a shared communication goal.
