Head injuries in children

child with bruise on foreheadChildren often bump their heads, because they are active, sometimes fall over, and enjoy rough-and-tumble play. They may get hit on the head while playing with other children. Fortunately, they mostly injure the outside of their heads, not their brains.

The term "head injury" refers to injuries you can see on a child's scalp as well as internal injuries to their brain. Brain injuries are sometimes called traumatic brain injuries, and concussion is sometimes called a minor traumatic brain injury.

Our foreheads and scalps have a very good blood supply. Knocks or injuries to these areas often cause bleeding under the skin. When the bleeding is mainly in one area, it causes swelling and bruising, which appears as an "egg" or swelling on a child's head. It may take days or even a week to disappear. While these can be scary-looking, they usually aren't dangerous.

Even a small head bump can cause a large swelling.

Treating head injuries in children

If your child has bumped their head, you should take them to a doctor if they:


Phone 111 for an ambulance if your child has hit their head and isn't behaving normally afterwards. Always take your child to a doctor if you think someone may have hurt them on purpose.

If your child has bumped their head and they are not a baby, have not been knocked out, and seem to be alert and behaving normally, keep a close eye on them for 24 hours. If you notice any of the signs above, take them to a doctor straight away.

Immediately after the injury:

Your child may cry or be distressed. This is normal, and most children will settle down within 15 minutes as long as they get the right attention and reassurance. If they don't settle, take them to a doctor.

If the accident happened close to bed or nap time and your child goes to sleep afterwards, check them a few times while they sleep.

Try to wake your child – they should grumble a bit and try to go back to sleep. If they seem very drowsy, even when you have tried to wake them by sitting them up, see your GP or dial 111 for an ambulance.
