Developmental Language Disorder in Children

What Is Developmental Language Disorder?

Developmental language disorder describes a child whose understanding or use of spoken or written language falls clearly behind what we expect for their age. It affects more than vocabulary. It also affects how a child builds sentences, follows grammar rules and keeps a story or explanation clear. A child can have typical overall intelligence and still have language skills well behind their classmates.

Specialists estimate that, on average, one or two children in every classroom have this disorder. Yet many families never notice it. That is why early identification matters so much for a child's learning and social development.

When our therapist looks at this disorder, they look beyond what your child says. They also look at how your child processes language. This helps to separate difficulties that look alike on the surface but need different support.

Signs to Look For

One of the most common signs is difficulty putting sentences together. Another is leaving out or mixing up tense endings. In English, a child might say "Yesterday I play outside" or "She go to school". Your child may also find long sentences hard to understand, or struggle to follow instructions.

Watch also for trouble finding words, frequent fillers such as "thing" or "stuff", and stories told out of order. Some children hold back in social settings because of these difficulties. A fear of saying something wrong can make them quiet and shy.

At school age, these signs can show up as reading and writing difficulties. Reading builds on a strong base of spoken language. When parents notice the signs early, it helps to protect later learning.

In some children the signs are subtle. Your child may cope well in everyday chat but struggle with long explanations in class or with written questions. Teachers often spot these quieter signs before parents do.

Causes and Risk Factors

In many cases specialists cannot point to one clear cause. A family history of similar language difficulties is one of the main factors that raises the risk.

Premature birth, low birth weight and repeated middle ear infections can also affect language development. Please do not confuse this disorder with low intelligence, poor parenting or neglect. Many children with typical intelligence have developmental language disorder.

Some researchers think small differences in how the brain's language areas work play a part. These differences affect the speed of language processing, not a child's general ability to learn. With the right support, many children keep pace with their peers in other areas.

Parents often ask about the home environment. Little talk at home or few books can slow language development. On their own, though, they do not cause a true developmental language disorder. During the assessment our therapist separates environmental factors from the disorder itself. This way your family can take the right next step without needless worry.

How We Assess Your Child

At the first meeting our therapist observes your child in play and conversation and talks with you in detail. The assessment is based on observation, play and a parent interview, not on standardised tests. We look at understanding and expression separately. We note vocabulary, sentence length, grammar and how clearly your child tells a story.

Where needed, we also take a developmental history and may suggest a hearing check. This shows whether the language difficulty is linked to another condition, such as autism or hearing loss. After the assessment we prepare an individual therapy plan. Each session at our centre lasts 40 minutes.

The assessment usually takes more than one meeting. In the first session our therapist observes and plays with your child. In the second, we share what we found and set therapy goals together with you. This two-step approach helps you understand the process and take an active part in therapy. These meetings and all progress updates can be held in English.

Receptive and Expressive Language Disorder

In receptive language disorder, a child struggles to understand what they hear or read. They may not follow instructions, or they may give answers that do not fit the question.

In expressive language disorder, understanding is relatively intact, but the child finds it hard to put thoughts into words. Some children have both types together. This is called mixed receptive-expressive language disorder. During the assessment our therapist identifies which area is most affected and shapes the therapy goals around it.

Our Therapy Approach

Our therapist combines play-based activities with structured language practice. Starting from your child's interests, they build vocabulary, sentence structure and storytelling step by step.

For children who struggle to find words, category and similarity games work well. A question such as "Which fruits are red?" helps the brain reach stored words faster. For sentence building, our therapist uses picture story cards. These guide your child towards longer and more complex sentences, one step at a time.

At the end of each session, our therapist shows you practical techniques to use at home. This carries new skills into daily life and helps them last. To see how this links with the DIR/Floortime approach, visit our Floortime therapy page. For an overview of the whole process, see our speech and language therapy page.

When Should Therapy Start?

Therapy that starts early tends to bring faster results, because a young brain is especially open to learning language. If you have concerns, we recommend an assessment from around age 3 to 4.

Therapy also brings clear benefits when the disorder is noticed at school age. Whatever your child's age, you can book an assessment as soon as you notice the signs.

DLD in Children Learning Turkish and English

Many families who come to us are raising children with Turkish and English, or with English and another home language. Learning two languages does not cause developmental language disorder. A bilingual child may know some words in only one language and may mix both languages in one sentence. Both are normal.

The two languages also work differently. Turkish adds endings to words to show tense and meaning, and it usually puts the verb at the end of the sentence. English uses small separate words and puts the verb after the subject. While a child is learning both, some mix-ups in word order or missing small words in English are expected.

The key question is whether the difficulty shows up in both languages. A child who is weaker only in the language they hear less is usually showing a normal exposure pattern. A child who struggles with sentences and understanding in both languages needs a closer look. Our therapist asks which languages your child hears at home and at school, and looks at both wherever possible. You can read more on our bilingual children page.

How Parents Can Help

Parents are the most important part of therapy for developmental language disorder. Repeat what your child says and add a little more. Give them time to think, and listen patiently. These small habits support language growth.

Talking through daily events together and building stories with picture books also help. At dinner, for example, ask your child to tell you about their day in order. This strengthens storytelling skills in a natural way.

Limit screen time too, because passive watching cannot replace real back-and-forth talk. Play together instead, ask questions and wait for the answers. This invites your child to use language actively. After the assessment our therapist suggests home techniques that suit your child and reviews progress with you at regular intervals. In bilingual homes, rich talk in either language helps, and you do not usually need to drop one language.

Links with Other Developmental Conditions

Developmental language disorder sometimes appears alongside autism spectrum disorder, attention difficulties or a specific learning difficulty. That is why our therapist looks at social interaction and attention, as well as language, during the assessment.

In autism, language difficulty usually comes with social communication difficulty. In developmental language disorder alone, the child still wants to interact with others. This difference matters when setting the right therapy goals. For more on autism and language, see our Language Development in Autism page.
