It's normal for children to feel worried or anxious from time to time – such as when they're starting school or nursery, or moving to a new area.
But for some children, anxiety affects their behaviour and thoughts every day, interfering with their school, home and social life.
This is when you may need professional help to tackle it.
Signs to look out for in your child are:
Separation anxiety is common in younger children, whereas older children and teenagers tend to worry more about school or have social anxiety.
If your child is having problems with anxiety, there's plenty you can do to help.
Above all, it's important to talk to your child about their anxiety or worries.

Many children at different ages may have anxieties that will go away after a while, with your reassurance.
However, it's a good idea to seek professional help or reassurance yourself if your child is constantly anxious and:
An appointment with a GP is a good place to start.
You can talk to the GP on your own or with your child, or your child might be able to have an appointment without you.
If the GP thinks your child could have an anxiety disorder, they may refer them for an assessment with your local children and young people's mental health services (CYPMHS).
Specialist CYPMHS are NHS mental health services that focus on the needs of children and young people. CYPMHS workers are trained to help young people with a wide range of problems, including anxiety.
If your child does not want to see a doctor, they may be able to get help directly from a local youth counselling service. For more information, visit Youth Access.
The type of treatment offered will depend on your child's age and the cause of their anxiety.
Counselling can help your child understand what's making them anxious and allow them to work through the situation.
Cognitive behavioural therapy (CBT) is a talking therapy that can help your child manage their anxiety by changing the way they think and behave. Learn more about CBT.
Anxiety medicines may be offered to your child if their anxiety is severe or does not get better with talking therapies. They're usually only prescribed by doctors who specialise in children and young people's mental health.
Some children are simply born more anxious and less able to cope with stress than others.
Children can also pick up anxious behaviour from being around anxious people.
Some children develop anxiety after stressful events, such as:
Children with attention deficit hyperactivity disorder (ADHD) and autistic spectrum disorders are more likely to have problems with anxiety.
