After a child’s concussion, the most important steps are monitoring for danger signs, limiting screen time for the first 48 hours, and allowing a brief period of rest before gradually reintroducing light activity. Most children recover within two to four weeks, but how you manage the first few days can meaningfully affect how quickly your child feels like themselves again.
Watch for These Danger Signs First
Before anything else, you need to rule out a more serious brain injury. In the hours after your child hits their head, watch for these red flags that require an immediate call to 911 or a trip to the emergency room:
- Seizures or convulsions (shaking or twitching)
- Repeated vomiting (not just once)
- Loss of consciousness, increasing drowsiness, or inability to wake up
- One pupil larger than the other or double vision
- Slurred speech
For infants and toddlers, the same signs apply, plus two others: crying that won’t stop no matter what you do, and refusing to nurse or eat. These warning signs can appear within minutes or develop over the first 24 to 48 hours, so stay attentive even if your child initially seems fine.
The First 48 Hours: Rest and Screen Limits
The old advice was to keep a concussed child in a dark room for days. That’s no longer the recommendation. Current guidelines call for “relative rest,” which means avoiding vigorous physical activity and anything that clearly makes symptoms worse, but not complete isolation or inactivity.
One thing that does deserve strict limits: screens. A randomized study of adolescents and young adults found that those who avoided screens for the first 48 hours after a concussion recovered faster and were more likely to have their symptoms fully resolved by day 10. The group that used screens as tolerated took longer to feel better. The abstinent group still averaged 5 to 10 minutes of daily screen time for basic tasks, so perfect avoidance isn’t the goal. The goal is a dramatic reduction: no scrolling, no video games, no binge-watching for two days.
This is a hard ask for kids whose lives revolve around phones and tablets, but 48 hours of boredom is a worthwhile trade for a shorter recovery. After those first two days, you can let your child gradually reintroduce screens based on how they feel. If looking at a phone brings back headaches, that’s a signal to wait longer.
Sleep and Monitoring at Night
Let your child sleep. Sleep is restorative after a brain injury, and there’s no need to keep them awake. However, it’s reasonable to check on them periodically during the first night, especially in the first few hours. You’re looking for the danger signs listed above: an inability to be woken up, vomiting, or unusual breathing. If your child wakes up normally when you rouse them and seems coherent, you can let them go back to sleep.
Managing Headaches Safely
Headaches are the most common symptom after a concussion and can persist for days or even weeks. For pain relief, acetaminophen (Tylenol) is the recommended option. Avoid ibuprofen (Advil, Motrin) and aspirin, because these medications can increase the risk of bleeding, which is the last thing you want when dealing with a head injury. Check with your child’s doctor about appropriate dosing before giving any medication.
Why Light Activity Helps Recovery
Once the first day or two of relative rest has passed, gentle movement actually speeds recovery. This is one of the biggest shifts in concussion management over the past decade. Researchers used to believe the brain needed complete rest until all symptoms disappeared. That turns out to be wrong.
A study of concussed adolescents found that those prescribed light aerobic exercise (like walking or easy stationary biking for 20 minutes a day) starting within the first week recovered in a median of 13 days. Those told to rest recovered in 16 days. Only 4% of the exercise group experienced a delayed recovery lasting 30 days or more, compared to 13% of the rest group.
The key is keeping the intensity below the level that triggers symptoms. If your child starts walking and their headache gets significantly worse, that’s too much. A gentle 10- to 15-minute walk that feels comfortable is exactly right. Think of it as moving enough to get the heart rate slightly elevated without pushing into discomfort.
Getting Back to School
Returning to school is often harder than returning to sports, because classrooms are full of concussion triggers: bright lights, noisy hallways, screens, sustained concentration. Most children don’t need to stay home for weeks, but they do need accommodations during recovery.
Common school accommodations that help include:
- Modified attendance: half days or starting with just a few classes
- Breaks as needed to rest in a quiet space
- Reduced homework and extra time on assignments or tests
- Permission to wear sunglasses or earplugs if light or noise triggers symptoms
- Limited in-class screen time
- Early or late transitions between classes to avoid crowded hallways
- Access to water and snacks throughout the day
- Alternative methods for taking notes or tests, such as oral exams or having a classmate share notes
If your child’s symptoms last beyond a couple of weeks, a formal 504 Plan can put these accommodations in writing so they’re legally protected. Talk to your child’s school nurse or guidance counselor early. You don’t need to wait until things become a problem.
The Six Steps Back to Sports
Returning to sports follows a structured, six-step progression, and your child needs a healthcare provider’s approval before starting it. Each step takes at least 24 hours, and your child should only move forward if they have no new symptoms at their current step.
- Step 1: Back to regular daily activities like school
- Step 2: Light aerobic activity (5 to 10 minutes of walking, light jogging, or an exercise bike; no weight lifting)
- Step 3: Moderate activity with more head and body movement (moderate jogging, lighter-than-usual weightlifting)
- Step 4: Heavy non-contact activity (sprinting, regular weightlifting, sport-specific drills)
- Step 5: Full-contact practice in a controlled setting
- Step 6: Return to competition
If symptoms return at any step, your child drops back to the previous step and waits another 24 hours before trying again. Rushing this process is one of the most common mistakes, and it’s also one of the most dangerous. A second concussion before the first has healed can cause far more severe damage.
How Long Recovery Actually Takes
You’ll often hear that most concussions resolve in 7 to 14 days. That’s true for some children, but the reality is messier. In one study tracking daily symptoms in children, about 48% recovered within 14 days, while 52% took longer. Roughly a quarter of children fell into a “moderate but persistent” pattern where symptoms started at a medium level and barely improved over several weeks, with some still reporting symptoms at 45 days. Another 16% had high initial symptoms that also persisted for over a month.
Younger children, girls, and children with a history of prior concussions tend to take longer to recover. If your child is still symptomatic after three to four weeks, that doesn’t mean something went terribly wrong. It means they’re in a common recovery pattern and may benefit from more structured treatment, like a supervised exercise program guided by a concussion specialist.
Mood and Behavior Changes to Expect
Physical symptoms like headaches and dizziness get most of the attention, but emotional and behavioral changes are just as common and often catch parents off guard. Your child may become noticeably more irritable, anxious, or tearful in the days and weeks after a concussion. Some children become withdrawn. Others act out with uncharacteristic aggression or impulsivity.
These changes have a biological basis. Brain-injured children are significantly more likely to develop new mood or anxiety symptoms than children with other types of injuries, like broken bones. One study found that 46% of children hospitalized for brain injuries (ranging from mild to severe) developed a new mood or anxiety disorder within six months, compared to 14% of children with orthopedic injuries. Overanxious behaviors are particularly common: worrying about performance, seeking constant reassurance, and fretting about events before they happen.
For mild concussions, these behavioral shifts typically improve within the first few months. But if irritability, sadness, or anxiety lasts beyond a few weeks or starts interfering with friendships and school, it’s worth raising with your child’s doctor. Novel depressive disorders can emerge in 10 to 25% of school-aged children within two years of a brain injury, and early recognition makes treatment more effective. Pay attention to personality changes in the first three months after injury, since that’s when they most commonly appear.
