Common Red Flags by Age for Speech and Language

Common Red Flags by Age

Every child develops at their own pace.

Small differences are normal.

Red flags are not labels.
They are gentle signals that it may be helpful to look a little closer.

Speech or Language?

Sometimes the difficulty is mainly about sounds.
Sometimes it is about understanding or using words.

When to Take the Next Step

If one or more red flags feel familiar, it does not mean something is seriously wrong.

It simply means it may be helpful to talk to someone.

In the UK, you can usually start with:

Your GP
Your health visitor
Your child’s nursery

You Know Your Child Best

Parents often sense when something feels different.

You do not need to wait until you are completely certain.

Early advice can provide reassurance, practical strategies, or further support if needed.

Asking questions is not overreacting.
It is caring.
