My Child Hit Their Head: When to Worry (Illinois 2026)

Published: June 17, 2026

Call 911 now for: loss of consciousness · repeated vomiting · a seizure · unequal pupils · clear fluid or blood from the nose or ears · a child you cannot fully wake.

Most childhood head bumps are minor. Seek emergency care if your child lost consciousness, vomits more than once, has a seizure, will not wake fully, shows unequal pupils, leaks clear fluid or blood from the nose or ears, or grows confused or unusually drowsy. When in doubt, call your pediatrician or 911. This is general information, not medical advice.

Your child fell off the bed, came off the monkey bars, or took a hard knock in the car, and now you are watching them for every sign that something is wrong. The reassuring part first: the large majority of childhood head bumps are minor, and most children who hit their heads are completely fine. The job in the first hours is to know which signs mean a child needs to be seen right away, and which mean you can watch carefully at home.

This guide walks through the warning signs that warrant emergency care, what to watch for over the next 24 to 48 hours, and, because head injuries are sometimes caused by someone else’s carelessness, what Illinois law says about a child’s injury claim. It is written for parents, not lawyers, and it is not a substitute for medical care.

What are the emergency warning signs after a child hits their head?

Go to the emergency room or call 911 if your child shows any of the following. The U.S. Centers for Disease Control and Prevention (CDC) HEADS UP program and the American Academy of Pediatrics (AAP) treat these as red flags:

Loss of consciousness, even for a few seconds
Vomiting more than once
A seizure or convulsion
A headache that keeps getting worse
Unequal pupil sizes, or eyes that will not focus
Clear fluid or blood draining from the nose or ears
Slurred speech, weakness, numbness, or trouble walking
Unusual drowsiness, or a child you cannot fully wake
Confusion, not recognizing people or places, or acting strangely

For a baby or toddler who cannot tell you how they feel, also watch for a bulging soft spot, inconsolable crying, refusing to nurse or eat, or a change in the way they normally move an arm or leg.

If any of these appear, do not wait. These can be signs of bleeding inside or around the brain, which can develop in the minutes or hours after the injury. Symptoms of a brain bleed after hitting the head sometimes show up late, which is why the next 48 hours matter.

My child seems okay. What should I watch for over the next two days?

A child can look fine right after a fall and still develop symptoms later. For the first 24 to 48 hours, keep them within sight and check on them periodically, including while they sleep. It is fine to let a tired child rest. What you are watching for is a change.

Call your pediatrician, or return to the ER, if your child:

Becomes harder to wake, or sleeps far more than usual
Starts vomiting after an initial calm period
Develops a worsening headache
Becomes more confused, irritable, or “not themselves”
Loses interest in favorite toys, food, or activities
Has any trouble with balance, vision, or speech

A concussion is a real injury even when a scan looks normal. Children may be slower to recover than adults, and symptoms like headaches, sensitivity to light, irritability, and trouble concentrating can last days or weeks. Rest, a gradual return to school and screens, and follow-up with your pediatrician are the standard path.

When is a child’s head injury more than an accident?

Sometimes a child is hurt because an adult or a business did not take reasonable care. Illinois law recognizes that children cannot protect themselves the way adults can, and it holds the people responsible for them to a standard built around that reality. Common situations include:

A daycare or babysitter that failed to supervise
A school or sports program that ignored a known hazard or a concussion protocol
An unsafe property: an unguarded pool, a broken railing, a fall hazard a property owner knew about
A car crash in which your child was a passenger
A defective product, such as a car seat or playground equipment that failed

In Illinois, a property owner’s duty to a child is measured by the ordinary rules of negligence, with the central question being whether harm to a child was reasonably foreseeable. The old “attractive nuisance” label was replaced decades ago by this foreseeability standard in Kahn v. James Burton Co. A licensed daycare owes the children in its care reasonable supervision, and a daycare’s failure to supervise that leads to a head injury can be the basis of a claim. None of this turns a normal childhood tumble into a lawsuit. It matters only when someone who owed your child care did not provide it.

What does Illinois law give a parent and child after a serious head injury?

If another person or business caused your child’s injury, Illinois law treats the child’s claim differently from an adult’s in several important ways. The framework below is current as of June 2026.

The deadline is longer for a child, but do not rely on it. The general deadline to file a personal injury claim in Illinois is two years (735 ILCS 5/13-202). For a child, that clock is paused: under 735 ILCS 5/13-211, a minor generally has until two years after their 18th birthday, meaning until age 20, to bring a personal injury claim. There is a separate and shorter rule when the injury involves medical care: under 735 ILCS 5/13-212(b), a claim for medical negligence involving a child must be brought within eight years of the act, and in no event after the child turns 22. Evidence fades long before any of these deadlines, so early documentation matters.

A parent has a separate claim for the medical bills. Because Illinois parents are responsible for a child’s medical expenses under the Family Expense Act (750 ILCS 65/15), the right to recover those bills from the at-fault party belongs to the parent, alongside the child’s own claim for the injury. That claim is tied to the child’s claim and follows the same deadline under 735 ILCS 5/13-203.

A child’s settlement is supervised by a court. A parent cannot simply sign away a child’s claim. Under the Probate Act (755 ILCS 5/19-8), an Illinois court must review and approve any settlement of a minor’s injury claim, and the proceeds are protected for the child rather than paid out freely. This is a safeguard, and it is one reason an insurance adjuster’s quick offer to a parent is not the end of the story.

The point is not to alarm. Most children who hit their heads need a watchful parent and nothing more. But when a child’s serious head injury traces back to someone else’s carelessness, Illinois law gives the family real protections, and the early days are when evidence is preserved and the child’s rights are protected.

Frequently Asked Questions

How do I know if my child has a concussion?

Watch for headache, dizziness, nausea, sensitivity to light or noise, confusion, balance problems, irritability, or seeming “foggy” or slow. A concussion is a brain injury that can be present even when a CT scan looks normal. If you suspect one, have your child evaluated by a doctor and keep them out of sports until a medical provider clears them.

Should I let my child sleep after they hit their head?

Yes. The old advice to keep a child awake is outdated. Rest is good for a healing brain. What matters is being able to check on them. Look in periodically over the first 24 to 48 hours, and seek care if they become unusually hard to wake, start vomiting, or seem more confused.

When should a child’s head injury go to the ER instead of the pediatrician?

Go to the ER or call 911 for loss of consciousness, repeated vomiting, a seizure, unequal pupils, clear fluid or blood from the nose or ears, slurred speech or weakness, or a child you cannot fully wake. For milder symptoms that you want checked, your pediatrician is the right first call.

My child was hurt at daycare. Do I have a claim in Illinois?

Possibly. A licensed Illinois daycare owes the children in its care reasonable supervision, and a failure to supervise that causes a head injury can support a claim. Whether a particular injury was preventable depends on the facts. Document what happened, get your child medical care, and ask the daycare for an incident report.

How long do I have to file an injury claim for my child in Illinois?

Longer than for an adult. A child generally has until two years after turning 18 to file a personal injury claim under 735 ILCS 5/13-211. Claims involving medical negligence have a separate, shorter rule under 735 ILCS 5/13-212(b). Because evidence disappears long before those deadlines, it is best not to wait.

Can an insurance company settle directly with me for my child’s injury?

Not freely. Under 755 ILCS 5/19-8, an Illinois court must approve a settlement of a child’s injury claim, and the money is protected for the child. A quick offer from an adjuster is not the final word, and you are entitled to understand the full value of the claim before anything is resolved.
