Many people wonder whether children or teenagers can develop BPD. It is a common question, especially for parents or carers who notice strong emotions, sudden mood changes or sensitivity in young people.
The simple answer is that BPD cannot usually be diagnosed in young children, but it can be diagnosed in teenagers. Emotional patterns can also begin early, even if the full diagnosis comes later.
This article covers:

- Where to get help
Can BPD be diagnosed in children?
In the UK, BPD is not diagnosed in young children. Their emotions, identity and coping skills are still developing rapidly, and what looks like BPD traits can often be part of normal growth.
That said, some children do show signs of emotional sensitivity or intense reactions that might later be linked with BPD. These signs do not guarantee a diagnosis in adulthood, but they can show that extra emotional support may be helpful.
Can teenagers be diagnosed with BPD?
Yes. BPD can be diagnosed in teenagers, usually from around 12–13 years old onwards, but more commonly in the later teens. At this stage, emotional patterns are clearer and more stable, which makes diagnosis more accurate.
A teenage diagnosis does not mean their adult life is fixed. With the right support, many young people improve significantly and learn strong emotional skills.
Signs to look out for
Young people may show signs that look similar to BPD traits, such as:
- Strong emotions that rise and fall quickly
- Fear of being abandoned or rejected
- Intense friendships that change suddenly
- Anger that feels hard for them to control
- Impulsivity, such as risky behaviour or sudden decisions
- Feeling empty, hopeless or unsure who they are
- Self harm or thoughts of harming themselves
These signs can also appear for many other reasons, including trauma, stress, neurodiversity, depression or anxiety. They do not automatically mean BPD, but they do mean a young person may need understanding and support.
Why early support matters
You do not need a diagnosis to give a young person the help they need. Support during childhood and the teenage years can make a huge difference. Early help can:
- Teach healthier coping skills
- Reduce harmful behaviours
- Improve communication and trust
- Strengthen relationships
- Lower the long term impact of emotional stress
Young people often respond well to clear boundaries, calm routines and consistent reassurance.
Helpful ways to support a young person
Small steps can help a child or teenager feel more stable:
- Listen without judgement
- Give simple explanations when emotions run high
- Keep routines steady and predictable
- Encourage breaks, rest and calming activities
- Help them name their feelings
- Make school or social stress easier where possible
- Seek professional support when needed
Parents and carers may also benefit from support, especially if the situation feels overwhelming.
When to seek help
You should reach out for professional support if a young person:
- Self harms or talks about harming themselves
- Feels persistently hopeless
- Has intense emotional outbursts that affect daily life
- Uses alcohol or drugs to cope
- Struggles with school, friendships or home life
- Seems increasingly withdrawn
A GP, school counsellor or mental health service can guide you to the right support. Early help is more important than a diagnosis.
Summary: Can children and teens have BPD?
Children are not usually diagnosed with BPD, but teenagers can be. Some young people show early signs of emotional difficulty, and with the right support these patterns can improve over time.
Focusing on calm routines, open communication and professional help when needed can make a real difference.
