Head bumps are extremely common in childhood. Babies tumble while learning to sit and walk, toddlers run into furniture, and older children fall while playing sports, cycling, or climbing.
Most minor head injuries do not cause serious problems.
However, because the brain is protected inside the skull, parents cannot judge the seriousness of every injury simply by looking at the outside of the head.
A child may have only a small bump but develop symptoms that need medical attention. Conversely, a large-looking lump on the scalp can sometimes occur after a relatively minor injury.
What matters is what happened and how the child behaves afterwards.
Immediately After a Head Injury
Stay calm and assess your child.
Check whether they are conscious, breathing normally, and responding appropriately.
If the child is unconscious, has serious breathing problems, is having a seizure, or has suffered a major injury, contact emergency services immediately.
Avoid unnecessary movement if a neck or spinal injury is possible.
If the injury appears minor and the child is alert, comfort them and look for cuts, swelling, or other injuries.
What Is a Minor Head Injury?
A minor bump may cause temporary pain, crying, mild swelling, or a small bruise.
Children often become upset immediately after falling because they are frightened as well as hurt.
After settling, a child with a minor injury may return relatively quickly to normal behaviour.
However, continue monitoring them because some symptoms can develop later.
If you are uncertain about the force of the impact or your child’s symptoms, seek medical advice.
Treating a Bump or Swelling
A wrapped cold pack or cool compress may help reduce discomfort and swelling.
Never apply ice directly to the skin.
If there is a minor cut, control bleeding with appropriate first aid.
Pain relief may sometimes be appropriate, but follow age-appropriate medical or product guidance and seek professional advice if uncertain.
What Is Concussion?
A concussion is a type of brain injury that can occur after a blow or jolt to the head or body.
A child does not need to lose consciousness to have a concussion.
Possible symptoms include:
▪ Headache
▪ Dizziness
▪ Nausea
▪ Balance problems
▪ Confusion
▪ Difficulty concentrating
▪ Sensitivity to light or noise
▪ Unusual tiredness
▪ Memory problems
Younger children may not be able to describe these symptoms clearly and may instead become irritable, unusually quiet, clumsy, or different from normal.
Loss of Consciousness
Loss of consciousness after a head injury requires careful medical assessment.
Even a brief episode should not simply be ignored because the child later appears normal.
If a child remains unconscious, is difficult to wake, or does not respond normally, call emergency services immediately.
Keep the child safe and follow emergency instructions.
Avoid unnecessary movement if there may also be a neck or spinal injury.
Vomiting After a Head Injury
Some children may vomit after a head injury, particularly when they have been crying intensely or are distressed.
Repeated vomiting is more concerning.
Seek medical advice if your child vomits after a head injury, particularly if it happens repeatedly or occurs with headache, confusion, unusual sleepiness, balance problems, or other neurological symptoms.
Can a Child Sleep After Bumping Their Head?
Parents are often afraid to let children sleep after a head injury.
Sleep itself is not automatically dangerous after a minor injury.
However, a child who is unusually difficult to wake or increasingly drowsy may have a concerning symptom.
If your child is approaching their normal sleep time after an apparently minor injury, seek medical advice if you are uncertain about whether observation or waking checks are necessary.
Instructions may depend on the child’s age, injury, and symptoms.
Emergency Warning Signs
Seek urgent medical attention if your child develops:
▪ Loss of consciousness
▪ A seizure
▪ Repeated vomiting
▪ Severe or worsening headache
▪ Increasing confusion
▪ Difficulty walking or speaking
▪ Weakness or numbness
▪ Unusual behaviour
▪ Significant difficulty waking
▪ Blood or unusual clear fluid from the nose or ears
▪ Serious vision problems
A rapidly deteriorating child requires emergency care.
Babies Need Additional Caution
Babies cannot tell parents whether they have a headache, feel dizzy, or are confused.
Changes in feeding, crying, alertness, movement, or behaviour may therefore be important.
Seek medical advice after a significant head injury in a baby, particularly following a fall from height or when symptoms concern you.
A bulging or unusually tense soft spot, seizure, repeated vomiting, abnormal responsiveness, or other serious symptoms require urgent assessment.
Head Injuries During Sport
A child suspected of concussion should stop playing immediately.
Do not allow them to return to the game simply because they say they feel better after a few minutes.
A further head impact before recovery can be dangerous.
The child should receive appropriate medical assessment and follow a gradual return-to-school and return-to-sport plan according to professional guidance.
Rest and Recovery After Concussion
Concussion recovery should be guided by a healthcare professional.
Children may initially need adjustments to physical and mental activity depending on their symptoms.
Schoolwork, screens, reading, sport, and other activities may need temporary modification rather than complete prolonged isolation.
Recovery varies between children.
Do not rush a child back into contact sport before they have been appropriately cleared.
Monitor Behaviour
Parents often recognise subtle changes that may not appear on a checklist.
A child may seem unusually quiet, irritable, confused, clumsy, or simply “not themselves.”
Take these observations seriously after a head injury.
If your child’s behaviour concerns you, seek medical advice even if you cannot identify a specific physical symptom.
Frequently Asked Questions
Does a child have to lose consciousness to have a concussion?
No. Concussion can occur without loss of consciousness.
Can my child sleep after a minor head bump?
Sleep is not automatically dangerous after a minor head injury, but unusual difficulty waking or increasing drowsiness is concerning. Seek medical advice if you are unsure how your child should be monitored.
When is vomiting after a head injury concerning?
Repeated vomiting, particularly with headache, confusion, unusual sleepiness, or other neurological symptoms, requires medical assessment.
Can my child return to sport after a concussion?
A child with suspected concussion should stop playing immediately and return to sport only through an appropriate medically guided recovery process.
When is a head injury an emergency?
Loss of consciousness, seizure, repeated vomiting, worsening headache, confusion, weakness, difficulty speaking or walking, or significant difficulty waking require urgent medical attention.
