What to Do for a Concussion in Kids (2026)

When Your Child Hits Their Head — And You’re Not Sure If It’s Serious

If you're searching for what to do for a concussion in kids, you're likely holding your breath right now — maybe your 8-year-old just tumbled off the monkey bars, your teen took a hard hit during soccer practice, or your preschooler fell backward off a stool. That split-second panic? It’s valid. But what follows matters far more than the fall itself. Concussions are the most common traumatic brain injury in children — over 2 million U.S. kids visit emergency departments annually for head injuries, and up to 30% of those cases involve undiagnosed or mismanaged concussions (CDC, 2023). Unlike adults, children’s developing brains heal differently, recover slower, and are uniquely vulnerable to prolonged symptoms if managed incorrectly. This isn’t about ‘just resting’ — it’s about timing, monitoring precision, and knowing exactly when to escalate care. Let’s get you clarity, confidence, and control — starting now.

Step 1: Recognize the Signs — Because ‘They Seem Fine’ Is Often the Most Dangerous Illusion

Here’s what most parents miss: concussion symptoms rarely appear immediately. Up to 40% of pediatric concussions show delayed onset — meaning your child may laugh, walk, and even eat dinner normally… then vomit, grow confused, or collapse 3–6 hours later (American Academy of Pediatrics Clinical Report, 2022). Don’t rely on loss of consciousness — only 10% of concussions involve it. Instead, watch for these three tiers of warning signs:

Physical Red Flags (Seek ER within 1 hour): unequal pupil size, slurred speech, repeated vomiting, seizures, inability to recognize people or places, worsening headache that doesn’t respond to acetaminophen, or any loss of consciousness — even for seconds.
Cognitive & Emotional Shifts (Call pediatrician same day): confusion about time/date, slow responses, trouble remembering new information, sudden irritability, tearfulness without cause, or saying things like ‘my head feels weird’ or ‘everything’s too loud.’
Subtle Behavioral Clues (Monitor closely for 72 hours): increased napping, declining schoolwork despite effort, avoiding favorite games or screens, or clinging unusually to parents — especially in toddlers who can’t verbalize symptoms.

Dr. Elena Torres, pediatric neuropsychologist at Boston Children’s Hospital, emphasizes: “We see families who wait 48 hours because ‘he seemed okay at bedtime.’ By morning, he’s failing quizzes and crying at math homework — and that delay costs weeks of recovery time.” Trust your gut. If something feels off, it probably is.

Step 2: Immediate First Aid — What to Do (and Absolutely NOT Do) in the First 2 Hours

Contrary to popular belief, you should not wake a sleeping child every 2 hours — this disrupts critical neurochemical repair and worsens fatigue. AAP guidelines explicitly advise against it unless instructed by a clinician. Instead, follow this evidence-backed protocol:

Stop all activity immediately. No sports, no biking, no playground time — even if they insist they’re ‘fine.’ Physical exertion increases cerebral blood flow and metabolic demand, worsening inflammation.
Apply cold compress (not ice directly) for 15 minutes on and 15 off — reduces swelling and pain without risking skin injury.
Give only acetaminophen (Tylenol), never ibuprofen or aspirin, for first 48 hours — NSAIDs increase bleeding risk in micro-tears.
Keep lights low and noise minimal — but don’t isolate them in total darkness. Complete sensory deprivation delays visual and vestibular system recalibration. Dim lighting + quiet conversation is ideal.
Document everything: time of injury, observed behaviors, symptom onset times, and words your child used to describe discomfort. This log becomes invaluable for clinicians.

A real-world case: When 10-year-old Liam fell during lacrosse, his coach let him finish the quarter. By dinner, he couldn’t recall his sister’s name. His parents’ symptom log — noting ‘confused at 6:12 p.m., forgot lunch order at 6:47 p.m.’ — helped the neurologist confirm rapid symptom progression and rule out seizure disorder. Without that timeline, diagnosis would’ve taken days.

Step 3: The 7-Day Recovery Timeline — When to Rest, Return, and Reassess

Recovery isn’t linear — it’s layered. Pediatric concussions require staged reintegration based on symptom tolerance, not arbitrary calendar days. The Zurich Consensus (2023) and CDC’s HEADS UP protocol both endorse this 6-stage model, adapted for developmental appropriateness:

Stage	Symptom Threshold	Allowed Activities	Minimum Duration	Exit Criteria
Stage 1: Symptom-Limited Rest	No physical or cognitive exertion that worsens symptoms	Short walks (5–10 min), light stretching, no screens, no schoolwork	24–48 hours	Zero symptoms at rest for 24 consecutive hours
Stage 2: Light Aerobic Activity	Mild exertion OK; symptoms must resolve within 1 hour post-activity	Stationary bike, walking, gentle swimming — HR ≤ 70% max	24 hours	No symptom return during or after activity
Stage 3: Sport-Specific Exercise	No contact, no head impact; focus on coordination	Skating drills, throwing practice, non-contact soccer juggling	24 hours	No dizziness, headache, or nausea during drills
Stage 4: Non-Contact Training Drills	Increased complexity, moderate intensity	Team scrimmages without contact, agility ladder, reaction drills	24 hours	No cognitive fog or balance issues post-session
Stage 5: Full Contact Practice	Must tolerate full exertion with protective gear	Controlled contact drills under supervision	24 hours	Physician clearance required before Stage 5
Stage 6: Return to Play	Zero restrictions	Full game participation	N/A	Written clearance from licensed healthcare provider trained in concussion management

Note: School reintegration follows a parallel 5-stage academic protocol — starting with half-days, no testing, and gradual workload increases. Rushing either path risks ‘second-impact syndrome,’ a rare but catastrophic condition where a second concussion before full healing causes rapid brain swelling. According to Dr. Robert Cantu, co-founder of the Concussion Legacy Foundation, “90% of long-term post-concussion syndrome in kids stems from premature return to learning or sport — not the initial injury itself.”

Step 4: Navigating School, Screens, and Sleep — The Hidden Triggers Parents Overlook

Three everyday elements sabotage recovery more than anything else: unstructured screen time, academic pressure, and inconsistent sleep. Here’s how to manage each:

Screen Time: Why ‘Just One Video’ Is Neurologically Risky

Blue light suppresses melatonin, delaying sleep onset — and sleep is when glymphatic clearance removes neurotoxic waste (like tau proteins) from the brain. But more critically, screens demand intense visual processing and rapid attention shifting — both taxing the frontal lobe and vestibulo-ocular reflexes already strained by concussion. AAP recommends: No screens for first 48 hours; then, limit to 15-minute blocks with 30-minute breaks; avoid fast-paced content (YouTube Shorts, TikTok, competitive gaming). A 2021 JAMA Pediatrics study found kids who resumed unrestricted screen use within 72 hours took 4.2x longer to return to school full-time versus those on structured limits.

School Accommodations: How to Advocate Without ‘Coddling’

Under Section 504 and IDEA, concussed students qualify for temporary accommodations — but schools won’t initiate them unless you do. Request a formal ‘Concussion Management Plan’ with your school nurse and counselor. Key evidence-backed accommodations include: extended time on assignments (not tests), printed notes instead of copying from board, permission to leave class for headache relief, and exemption from PE/labs until cleared. Avoid phrases like ‘he needs extra help’ — instead say ‘his working memory is temporarily impaired per neurocognitive assessment’ to anchor requests in clinical reality.

Sleep Hygiene: The Non-Negotiable Foundation

Children need 9–12 hours nightly — but concussion disrupts circadian rhythm. Enforce strict sleep/wake times (even weekends), ban devices 90 minutes before bed, and use white noise to mask environmental triggers. Crucially: no melatonin supplements without pediatric neurologist approval — exogenous melatonin may interfere with natural hormone recalibration during recovery.

Frequently Asked Questions

Can my child sleep after a concussion?

Yes — and they should. Uninterrupted, quality sleep is essential for neural repair. However, monitor for red-flag symptoms before bedtime (vomiting, confusion, unequal pupils). If none are present, let them sleep. Check once before you go to bed yourself — not hourly. Waking them repeatedly disrupts restorative slow-wave and REM sleep, which are critical for synaptic healing.

Do kids need a CT scan or MRI after a concussion?

Almost never — and imaging should be avoided unless red-flag symptoms are present. CT scans expose children to ionizing radiation (increasing lifetime cancer risk), and MRIs rarely show acute concussion changes since it’s a functional, not structural, injury. As Dr. Laura D’Angelo, pediatric radiologist at CHOP, states: “A normal CT scan doesn’t rule out concussion — and an abnormal one usually means something far more serious than concussion.” Imaging is reserved for suspected skull fracture, bleeding, or progressive neurological decline.

How long does a concussion last in kids?

Most children recover fully within 4 weeks — but 20–30% experience persistent symptoms beyond that (post-concussion syndrome). Factors increasing risk include prior concussions, migraines, ADHD, anxiety disorders, or inadequate initial rest. If symptoms last >4 weeks, seek evaluation from a pediatric concussion specialist — not just a general pediatrician — for vestibular therapy, vision rehab, or cognitive behavioral therapy tailored to neuro-recovery.

Can my child return to sports after one concussion?

Yes — but only after full symptom resolution AND medical clearance. Crucially, the risk of a second concussion is 3–6x higher in the first 10 days post-injury. That’s why Stage 5 (full contact) requires physician sign-off. Also note: multiple concussions don’t ‘add up’ linearly — each subsequent injury lowers the threshold for future ones and prolongs recovery. Track all incidents in a personal health record; many schools now require documented clearance before athletic participation.

Are girls more likely to get concussions than boys?

Yes — and they report more severe and prolonged symptoms. Research in the British Journal of Sports Medicine shows female adolescents have 1.5–2x higher concussion incidence in soccer and basketball, likely due to neck muscle strength differences, hormonal influences on neuroinflammation, and underreporting in males masking true gender ratios. Girls also take ~20% longer to return to play on average. Tailor monitoring and expectations accordingly.

Common Myths About Childhood Concussions

Myth #1: “If they didn’t lose consciousness, it’s not serious.” Reality: Loss of consciousness occurs in fewer than 10% of pediatric concussions. Balance issues, emotional lability, and executive function deficits are far more common — and equally urgent indicators.
Myth #2: “Rest means doing nothing — lying in a dark room for days.” Reality: Strict rest beyond 48 hours actually delays recovery. Gradual, symptom-limited activity stimulates neuroplasticity. The CDC now advises ‘relative rest’ — balancing mental/physical load with recovery capacity.
