If you are noticing unexplained injuries, sudden secrecy, or behavior changes that may mean self-harm, this page can help you understand what to look for and what steps to take next with calm, informed support.
Start with what you are seeing right now so we can help you think through signs of self-harm in teens, adolescents, and children, and offer personalized guidance for your next step.
Parents searching for self-harm warning signs in teens are often responding to a pattern, not just one moment. You may see physical signs such as cuts, burns, scratches, or bruises that do not have a clear explanation. You may also notice your child hiding their arms, legs, or body, avoiding changing clothes around others, or becoming unusually protective of personal items. Emotional and behavioral shifts can matter too, including withdrawal, irritability, shame, sudden mood changes, or spending long periods alone after distress. Looking at the full picture can help you decide how urgent the concern may be.
Repeated cuts, burns, scratches, bite marks, bruises, or bandages without a clear reason may be physical signs of self-harm in children or teens. You might also notice blood on clothing, tissues, or bedding.
Wearing long sleeves or pants in warm weather, locking doors more often, hiding laundry, or becoming defensive when asked about injuries can be early signs of self-harm in kids and adolescents.
Behavior changes that may mean self-harm include pulling away from family, increased anger or sadness, hopeless comments, sudden shame, or a sharp drop in coping after stress, conflict, or social problems.
A single injury does not always mean self-harm. Several signs together, especially repeated injuries plus secrecy or emotional distress, are more important than any one detail alone.
If you are wondering how to tell if your child is self-harming, a calm, direct question is often more helpful than avoiding the topic. Focus on concern, not punishment or shock.
Pay attention to whether signs appear after arguments, school stress, friendship problems, bullying, or intense emotions. This can help you understand risk and prepare for a supportive conversation.
If your child has current injuries, talks about wanting to die, says they cannot stay safe, or you find evidence suggesting serious harm, seek immediate crisis support or emergency help. If the signs are less urgent but still concerning, it is still important to respond soon. Early support can reduce shame, improve communication, and help your child get appropriate care.
Stay calm, check for immediate medical needs, and reduce access to sharp objects or other means of injury if you believe there is active risk.
Use simple language such as, “I have noticed some things that make me concerned, and I want to understand what you are going through.” Listening matters more than having the perfect words.
An assessment can help you organize what you are seeing, understand whether the warning signs fit a concerning pattern, and identify the most appropriate next step for support.
Common signs include unexplained cuts, burns, scratches, bruises, frequent bandages, hiding the body with clothing, blood on personal items, secrecy, withdrawal, and mood or behavior changes that feel out of character.
Denial is common because many children and teens feel shame or fear. Look for repeated patterns over time, including physical signs, hidden sharp objects, clothing changes, and emotional distress. A calm, nonjudgmental conversation is usually more effective than repeated confrontation.
Some signs overlap across ages, but teens may be more skilled at hiding injuries and may show stronger secrecy, isolation, or emotional withdrawal. Younger children may show distress through behavior changes, avoidance, or confusion about their own actions.
No. Behavior changes can have many causes, including anxiety, depression, bullying, trauma, or other stress. But when behavior changes happen alongside unexplained injuries or secrecy, it is important to take the possibility of self-harm seriously.
Begin with a calm check-in, look for immediate safety concerns, and avoid reacting with anger or panic. If there is any sign of suicidal intent or serious injury, seek urgent help right away. Otherwise, use a structured assessment and connect with a qualified professional promptly.
