What to Look for If Your Toddler Fell Down the Stairs

Head injuries are the primary concern after a toddler tumbles down stairs, and the warning signs you need to watch for depend on the type and severity of the impact. Children under ten who fall on stairs experience more head and neck injuries than older kids and adults do, and toddlers in particular are vulnerable because their heads are proportionally large and heavy relative to their bodies.¹ Most stair falls end with nothing worse than bruises and tears, but a small percentage involve skull fractures, concussions, broken bones, or internal injuries that may not be immediately obvious. Knowing what to look for in the minutes, hours, and days after a fall can help you decide whether your child needs medical attention right away or careful watching at home.

Head Injuries Are the Top Priority

The single most important thing to assess after a toddler falls down stairs is whether they hit their head. A bump on the forehead that swells into a goose egg is common and, on its own, is not necessarily dangerous. What you are really screening for is something happening inside the skull: bleeding, swelling, or a fracture.

In one study of children who fell on stairs, about 2% had skull fractures, and every one of those fractures occurred in a child who had been dropped or who fell while being carried by an adult rather than tumbling on their own.² That pattern has shown up across multiple studies: infants and toddlers who fall from an adult’s arms on the stairs tend to sustain more serious head injuries than those who tumble down a few steps unassisted.³ The reason is straightforward: a child falling from an adult’s height hits the ground with more force than one who slides or rolls from step to step.

Signs of a potentially serious head injury to watch for include:

Loss of consciousness: Even a brief blackout after impact warrants an emergency department visit.
Vomiting: A single episode of vomiting right after a scare can be from crying, but repeated vomiting over the next few hours suggests rising pressure inside the skull.
Unusual drowsiness: If your toddler becomes hard to wake or seems abnormally sleepy beyond what you would expect given the time of day, get them evaluated.
A swelling that feels soft or boggy: A firm bump on the forehead is typical bruising; a soft, squishy swelling, especially on the side or back of the head, may indicate a fracture underneath.
Clear fluid from the nose or ear: This can signal a skull base fracture and is an emergency.
Unequal pupil size: If one pupil looks larger than the other, go to the emergency room immediately.
Seizure: Any seizure after a head impact needs urgent evaluation.

Intracranial bleeding from a stair fall is uncommon, but it can occur even in short-distance falls. One case report documented an infant who sustained a fatal subdural hematoma from a stairway fall, a finding that challenged the widespread assumption among clinicians that low-height falls in young children are always benign.⁴ Among children under two who suffered head trauma from falls, about 2% were found to have retinal hemorrhages, all associated with severe bleeding inside the skull that caused a shift in brain structures.⁵ These severe outcomes are rare, but they underline why the first 24 hours after a stair fall are the most critical observation window.

Why Concussion Signs Look Different in Toddlers

A concussion is a type of mild traumatic brain injury that does not always show up on a CT scan. In older children and adults, the hallmarks are headache, dizziness, confusion, and sensitivity to light. Toddlers experience the same brain injury but express it differently because they cannot describe their symptoms. Emergency physicians themselves acknowledge that diagnosing concussion in very young children is especially difficult because of limited verbal skills and unreliable exam findings.⁶

Instead of telling you their head hurts, a concussed toddler is more likely to show behavioral changes. Research on post-concussive symptoms in young children found that children under two were especially likely to show sleep disturbances and increased comfort-seeking at each assessment point after injury.⁷ Caregivers of injured children in this age range have also reported irritability, moodiness, and an increase in comfort-seeking behavior as the most prominent signs in the first days after a mild brain injury.⁸

In practical terms, the behaviors to watch for in the days following a stair fall include:

Increased clinginess: Wanting to be held constantly, refusing to play independently.
Irritability: Crying more than usual, being harder to soothe, or having tantrums that seem out of proportion.
Sleep changes: Sleeping more than normal, difficulty falling asleep, or waking up repeatedly during the night.
Appetite loss: Refusing food or bottles they normally accept.
Balance problems: A toddler who was walking steadily may seem wobbly or fall more frequently.

Any of these signs on their own could be a coincidence, but a cluster of them appearing in the days after a head impact deserves a call to your pediatrician. The challenge is that these behaviors overlap heavily with normal toddler fussiness, teething, or a disrupted routine, which is exactly why concussions in this age group get missed.

Bone Fractures You Might Not See Right Away

Not every stair fall is about the head. The extremities absorb impact too, and fractures are the second most common serious injury. Among children who sustained fractures from stair falls, roughly three-quarters involved arms or legs and about a quarter involved the skull.³

One fracture that is notoriously easy to miss in this age group is the so-called toddler’s fracture, a hairline break in the shinbone. It typically happens in children between one and four years old, often from a seemingly minor twist or stumble. The history of trauma is usually trivial, and the initial X-ray can look completely normal because the fracture line is so faint.⁹ The classic clue is a toddler who was walking fine before the fall and now refuses to bear weight on one leg or starts limping. If your child pulls their leg up and cries when you try to stand them, it is worth getting evaluated even if no swelling is visible. A repeat X-ray a week or two later sometimes reveals the fracture that the first one missed, because the healing process makes the break line easier to see.

Other fracture signs to look for include obvious swelling or deformity of an arm or leg, tenderness when you gently touch or squeeze a limb, and reluctance to use one arm (for instance, not reaching with the hand they usually favor).

Neck and Spine Injuries

Cervical spine injuries from household falls are rare in toddlers, but they do happen. A study identified eight children aged nine months to just under six years who sustained cervical spine injuries after falls from heights of less than five feet. All of them had limited range of motion of the neck or neck pain.¹⁰ In that group, the injuries ranged from rotary subluxation (where one of the upper neck vertebrae shifts out of alignment) to fractures of the second cervical vertebra.

Because toddlers cannot tell you “my neck hurts,” the signs are indirect. A child who suddenly refuses to turn their head to one side, holds their head tilted at an odd angle, or screams when you move their neck during a diaper change should be evaluated. If a toddler falls down a full flight of stairs and lands awkwardly, or if there was any tumbling that could have snapped the head forward or backward, keep them still and get emergency help rather than scooping them up and testing their range of motion yourself.

Hidden Abdominal Injuries

Abdominal injuries from stair falls are uncommon in toddlers, but they can be deceptive because internal organ damage sometimes produces no visible external bruising in the first hours. Research comparing accidental falls with non-accidental trauma found that children who fell were more likely to have solid organ injuries (to the liver, spleen, or kidneys), while patterns like hollow-organ or pancreatic injuries were more strongly associated with abuse.¹¹ That distinction is more relevant to emergency clinicians than to you at home, but it is worth knowing that a blow to the belly during a fall can injure internal organs.

Warning signs of an abdominal injury include persistent crying that seems focused on the belly, a distended or firm-feeling abdomen, vomiting that starts hours after the fall (rather than immediately), and blood in the stool or urine. If your toddler took a hard tumble and draws their legs up to their chest while crying, or if they refuse to let you touch their belly, these are reasons to seek medical evaluation.

How the Fall Happened Changes the Risk

Not all stair falls are equal. The circumstances matter a great deal in predicting how likely your child is to be seriously hurt. Biomechanics research has shown that children who fall from greater heights, hit harder surfaces, and have lower body mass tend to experience more severe injuries.¹²

Testing with crash-test dummies designed to mimic a 12-month-old found that feet-first falls from short distances (around two feet) carried a low risk of serious head injury regardless of the landing surface.¹³ The surface mattered more than you might expect: playground foam produced significantly lower head accelerations than wood, linoleum, or padded carpet.¹⁴ This means a toddler who slides down three carpeted steps on their bottom is in a very different risk category from one who tumbles head-first down a full hardwood staircase.

Questions that help you gauge risk when deciding whether to head to the emergency room:

How many steps? A tumble down two or three steps is lower risk than a fall down a full flight.
Were they being carried? As noted above, falls from an adult’s arms on stairs produce more force and a higher rate of skull fractures.
What did they land on? Hardwood, tile, or concrete at the base of the stairs is more dangerous than carpet.
How did they land? A head-first landing is higher risk. A child who slid or rolled step-by-step dissipates energy along the way.
Did they lose consciousness, even for a second? This alone is enough to warrant an emergency visit.

When to Go to the Emergency Room

Emergency physicians use clinical decision rules to help determine which children with head injuries need a CT scan. The most widely validated of these is the PECARN rule, which is the only one of the major pediatric head-injury decision tools that has been validated and that provides a separate algorithm for children under two.¹⁵ You do not need to memorize the algorithm, but knowing what it prioritizes can help you recognize red flags.

Go to the emergency room if your toddler has any of these after a stair fall:

Loss of consciousness
A seizure
Repeated vomiting (more than once)
A bulging soft spot (fontanelle) in an infant
Clear fluid leaking from the nose or ear
Inability to be consoled after 20-30 minutes
Not acting like themselves: unusually sleepy, confused, or staring blankly
Refusing to walk or use a limb
A visible dent or depression in the skull

Call your pediatrician (rather than necessarily rushing to the ER) if your child hit their head but is now acting normally, has a single episode of vomiting and then stops, develops a firm bump that does not seem to grow, or is fussy but can be comforted. Many pediatricians will ask you to do wake checks overnight: gently rouse your child every few hours while they sleep to make sure they respond normally. If at any point during the observation window they become harder to wake, vomit again, or develop new symptoms, escalate to the ER.

The Observation Window

Most dangerous complications from a head injury declare themselves within the first four to six hours, but some, particularly slow bleeds, can take up to 24 to 48 hours to produce symptoms. That is why the advice to “watch them” is not just a formality. During the first day after a fall, keep activities calm, avoid screen time that could mask headache-related irritability, and stay physically close enough to notice changes in behavior.

After the initial 48-hour window, post-concussive symptoms like sleep disturbance, irritability, and balance problems may persist for days or weeks, as the research on young children’s symptom patterns suggests.⁷ These ongoing symptoms do not usually signal a new emergency but do warrant follow-up with your pediatrician, especially if they interfere with eating, sleeping, or development milestones.

Preventing Future Falls

Once you have gotten through the immediate scare, preventing the next fall is worth your attention. A large case-control study found that the absence of stair gates more than doubled the odds of a child’s stair fall compared to having a closed gate in place. Leaving a gate open carried an even higher risk, roughly tripling the odds. Uncarpeted stairs and stairs without a mid-flight landing also increased risk, though to a smaller degree.¹⁶

The evidence points to a few practical steps: install gates at both the top and bottom of the stairs and keep them closed. A gate at the top is the higher priority because a fall from the top carries more force. Carpet or a non-slip runner on uncovered stairs reduces the energy of each step-to-step contact. If your staircase has a landing partway up, that landing acts as a natural speed bump that limits how far a child can tumble in a single stretch. And if you are carrying your toddler on the stairs, hold the railing with your free hand. The data on carried children sustaining worse injuries than those who fell independently makes this more than a generic safety tip.²

Parental Stress After the Fall

Almost every parent who has watched or heard their toddler tumble down stairs knows the wave of guilt and fear that follows. That emotional response is normal, and for most parents it fades. But research on parents of children who experienced accidental injuries found that close to 10% of parents showed clinically significant post-traumatic stress symptoms within two weeks of their child’s accident. By six months later, that number had dropped to about 6%, but the parents most at risk of lasting stress were those whose child was hospitalized for more than a day or who suffered a permanent physical impairment.¹⁷

If you find yourself replaying the fall, struggling to sleep, avoiding the stairs entirely, or feeling paralyzed by anxiety about your child’s safety weeks after the event, those feelings are worth mentioning to your own doctor. The stress parents carry after a child’s injury is real and well-documented, and it does not make you overprotective or weak to seek support for it. Your toddler needs you functioning well during their recovery, and ignoring your own stress does not help either of you.
