Bilingualism does not cause speech or language disorders. A consultation is worth considering when difficulties affect the child’s overall communication, appear in the language they know best, involve loss of skills, or raise concerns about hearing.
A bilingual child may know some words in Polish and others in the language used at home. They may understand one language more easily but answer more often in another. Looking only at Polish words can therefore create unnecessary concern or hide a genuine difficulty.
Do two languages delay speech development?
No. The American Speech-Language-Hearing Association states that using several languages does not cause or worsen a language disorder. Monolingual and multilingual children can have developmental difficulties, but bilingualism itself is not the cause.
Development in each language depends on when exposure began, how often the language is used, who speaks it, and where the child needs it. The dominant language may change after starting nursery, moving home, or spending more time with relatives. This does not mean that the child is confused or has forgotten the other language.
Consider the full repertoire
What is typical in bilingual development?
Mixing languages in one sentence is natural. A child may choose the word they know best or use most often in that situation. They might know food words in the home language and nursery activities in Polish. With time, children learn to adjust language to the person and setting.
Uneven skill is also expected. One language may have richer vocabulary, while another is used more in play. An accent or patterns transferred from another language do not by themselves show a disorder. The amount and quality of exposure must be considered.
When should a bilingual child see a speech therapist?
Using less Polish than peers who have always spoken Polish is not enough on its own. Consultation is appropriate when one or more of these signs appear:
- the child loses words or communication skills they used before;
- simple messages remain hard to understand even in the language the child knows best;
- vocabulary and gestures across all languages are very limited and communication is not progressing;
- learning words, building sentences, or holding a conversation is hard across the languages the child uses;
- close family members who know the home language also find speech very difficult to understand;
- the child responds inconsistently to sound, often asks for repetition, or has recurring ear problems;
- communication difficulties cause marked frustration or limit play and social participation.
Milestones guide a decision to seek advice but do not diagnose a child. If you are concerned about communication progress, read our guide to delayed speech development and speech therapy consultation.
Language difference or language disorder?
Weaker Polish after shorter exposure may be a natural language difference. A language disorder affects the child’s full repertoire, although signs do not have to look identical in every language. Languages differ in grammar, sound systems, and sentence structure.
One Polish-language test should not decide the diagnosis by itself. A fair assessment combines several sources of information and may examine what the child can learn when given appropriate support.
How should a bilingual child be assessed?
Assessment does not require the same standardised test in every language. It should, however, gather reliable information about every language the child uses. A speech therapist may combine:
- a history of when, where, and with whom the child uses each language;
- information about comprehension, expression, gestures, play, and communication at home and in nursery or school;
- observation and natural conversation or storytelling samples in the child’s languages;
- tools suited to the child’s language experience and dynamic assessment that examines response to brief teaching;
- work with a trained interpreter when the therapist does not speak the home language.
A test designed for one population cannot simply be translated and scored against the original norms. Languages have different structures, and the child’s experience affects performance. ASHA guidance on multilingual service delivery stresses the need to consider the full profile and the limits of each assessment tool.
How can parents prepare for the consultation?
Note which languages the child uses, when exposure began, who speaks each language, and the language of education. Examples of words and sentences from every language, information from nursery, hearing results, and a history of ear infections can all help.
If the clinic offers a secure way to share material, ask whether a short recording of natural conversation with a home-language speaker would be useful. Do not teach answers or drill Polish words before the visit. The therapist needs to understand everyday communication.
Our guide on preparing for a speech and language assessment provides a broader checklist.
How can families support their languages at home?
Speak to your child in the language that feels natural to you. Rich, spontaneous conversation offers more than an artificial switch to Polish simply because it is the nursery language. The home language supports family relationships and gives the child access to complete, varied communication.
- talk during daily routines and expand the child’s message with your own natural model;
- read, sing, and play in the languages used by the family;
- accept language mixing instead of asking for every word to be translated;
- offer contact with people who use each language confidently;
- tell nursery or school which languages the child uses and when exposure began.
There is no compulsory method for organising family languages. The one-parent, one-language approach suits some families but is not a condition for healthy development. Regular exposure, responsive conversation, and meaningful relationships matter more.
Why should hearing be considered?
Tell the therapist and doctor if the child responds inconsistently to sound, frequently asks for repetition, watches a speaker’s mouth, or has recurring ear infections. A normal newborn hearing screen does not rule out hearing loss that develops later. Hearing information helps distinguish limited language exposure from other causes of difficulty.
Bilingual speech therapy consultation in Gdansk
If difficulties appear across languages, the child loses skills, or communication causes marked frustration, there is no need to wait for them to “catch up in Polish”. When booking a pediatric speech therapy consultation in Gdansk, describe every language the child uses and ask how each will be represented in the assessment.
When spoken communication is very limited, the family can also support effective communication now. Read more about AAC for a child who is not yet speaking.

Learn more about this therapyFrequently asked questions
- Can bilingualism delay speech development?
- Using two languages does not cause a speech or language disorder. A child’s skills may be distributed across languages, so the full vocabulary and communication profile matter more than the number of words used in English or Polish alone.
- Should I worry when my child mixes languages?
- Usually not. Using a word from another language or switching languages is a normal part of multilingual development, especially when the child knows a particular word in only one language.
- Which language should parents use at home?
- Parents should use the language in which they communicate most naturally and richly. Families do not need to abandon the home language or follow a one-parent, one-language rule if it does not suit them.
- How can I tell whether the difficulty affects more than Polish?
- Consider comprehension, gestures, vocabulary, sentences, and conversation across all of the child’s languages. A disorder affects the child’s full language system, although signs may differ in form and severity between languages.
- How can a speech therapist assess a language they do not speak?
- The assessment may use a family interview, natural communication samples, information from nursery or school, and a trained interpreter. The therapist may also examine how the child learns with brief support instead of relying on one Polish-language test.
- Does my child need a hearing test before the consultation?
- Not every family needs the result before the first visit, but the speech therapist may recommend hearing assessment. It is especially important when a child responds inconsistently to sound, often asks for repetition, or has recurring ear problems.
