Understanding Language Delays in Children: When Parents Should Be Concerned

Language is one of the most important tools a child has to communicate, learn, and build  relationships. While it is normal for children to develop language at different rates, some may  show signs of a language delay or language disorder that go beyond typical variation.  Recognising the difference and knowing when to seek help can make a meaningful impact on a child’s long-term development.

What Is Language Delay and Language Disorder? 

Language delay refers to a slower-than-expected development in a child’s ability to understand or use language. Children with language delay usually follow the typical sequence of language milestones, such as saying first words, combining words, and asking questions—but they reach those milestones later than their peers. These children may simply need more time or support to catch up.

Language disorder, however, involves more persistent and often complex difficulties. Children with  a language disorder may struggle with receptive language, such as understanding what others say,  or expressive language, such as using words and sentences to express themselves—or both. Unlike language delay, language disorder does not follow the usual developmental path and often  requires long-term support from professionals.

These challenges can make it hard for a child to share ideas, ask for help, follow directions, or engage in conversation, all of which are critical for success in school and in everyday life.

Conditions That Can Affect a Child’s Language Development 

There are a variety of factors that can affect a child’s ability to develop language. One of the most common causes is developmental language disorder (DLD), a condition that affects language learning for reasons not linked to hearing loss, intellectual disability, or other identifiable medical issues.

Autism spectrum disorder (ASD) can also impact how a child understands and uses language. Many children on the spectrum experience delays in language development, and some may communicate in nonverbal ways or have unique patterns of speech.

Hearing impairments, even mild or temporary ones, can prevent a child from hearing language clearly during key developmental periods. Without consistent access to spoken language, it can be difficult for children to learn how language works.

Intellectual disabilities or neurological conditions such as cerebral palsy or traumatic brain injuries  can affect how the brain processes language, or how a child controls the muscles needed for  speaking.

Lastly, environmental factors can also contribute to language delays. These may include limited exposure to rich and responsive language interactions, or challenges faced in bilingual households without adequate support.

Recognising the Signs of Language Delay

While each child is different, there are some common signs that may indicate a language delay or disorder:

• Limited vocabulary compared to peers of the same age 

• Difficulty combining words into sentences 

• Trouble understanding and following directions 

• Difficulty answering questions appropriately 

• Frequent mistakes in grammar, such as incorrect verb use or word order 

• Sentences that are shorter or less complex than expected 

• Difficulty telling stories or explaining events 

• Speaking less than peers or avoiding talking altogether

If these signs persist over time, it may suggest that your child could benefit from professional  support to build their language skills.
