Developmental Language Disorder

Ages and stages

Children develop their speech, language and communication skills at different rates. However, knowing what is typical development can help you identify possible speech and language difficulties early.

Speech and Language UK have a handy set of ages and stages guidelines which can help you with this.

Below are some guidelines on how children typically develop their talking and understanding of words and sentences between these age ranges.

Some children struggle with learning to talk and understand words.

If you notice any of these things, talk to your child’s school or contact your local speech and language therapy helpline for advice. This is a confidential phone call with an experienced speech and language therapist. During the call, you will be given the opportunity to talk through your concerns and questions regarding your child’s development.

By 7 years old

Everyone develops skills at different rates, but typically children will be able to do the following:

Focus on one thing longer without being reminded
Follow and remember a story that is told over several days
Understand long instructions, for example, ‘Put our toys back in the cupboard, go upstairs and find your swimming things’.
Learn that the different words can mean the same thing, such as ‘minus’ and ‘take away’.
Talk for lots of different reasons, such as to share complex ideas, to solve problems or to tell jokes.
Use long sentences and put the correct endings on their words. For example ‘My teddy likes sitting on a bed because beds are softer’.
Use words like ‘so’ and ‘because’ to join their sentences together. For example, ‘It’s my birthday so I’m staying up late’.
Can take turns to talk in conversations with adults and children in lots of different situations, either with one person or in a group.
Talk clearly so that unfamiliar people can understand them almost all of the time. They might still make mistakes in tricky words, like saying ‘spash’ instead of ‘splash’.
Talk quite smoothly and don’t repeat the first sound in words or get ‘stuck’ trying to get a word out.
