Head Injury in Babies
Content reviewed against published AAP, CDC, Mayo Clinic guidelines
Last reviewed:
Head injuries in babies and toddlers are common as they learn to roll, crawl, and walk. Most are minor bumps that resolve with comfort and ice. However, infants are at higher risk for serious injury because their skulls are thinner, their neck muscles are weaker, and they cannot describe symptoms. Any fall from a significant height or forceful impact warrants careful observation.
Key takeaways
- Head injuries in babies and toddlers are common as they learn to roll, crawl, and walk.
- Most common cause: Falls from low height (rolling off bed, couch, changing table)
- Emergency: Loss of consciousness, even briefly
- Home care: Apply a cold compress or ice wrapped in a cloth for 20 minutes to reduce swelling
Possible Causes
When to Seek Help
Emergency — Call 911 or go to ER:
- Loss of consciousness, even briefly
- Seizure following head injury
- Blood or clear fluid leaking from ear or nose
- Unequal pupils or eyes not moving together
- Baby is limp, unresponsive, or extremely difficult to wake
- Visible skull deformity or depression
- Bulging fontanelle after head injury in infant
Urgent — See doctor today:
- Vomiting more than twice after head injury
- Progressively worsening drowsiness
- Fall from more than 3 feet (0.9 meters) in infant under 2
- Large swelling or bruise in infant under 3 months
- Persistent high-pitched or unusual crying
- Fall onto hard surface (concrete, tile) from significant height
Same-day appointment:
- Small bump (goose egg) with normal behavior afterward
- Single episode of vomiting right after crying hard
- Minor fall from low height with brief crying then return to normal
Monitor at home:
- Very short fall (less than 2 feet) onto soft surface with normal behavior
- Small bump while cruising furniture with immediate return to play
- Toddler bumps head on table edge, cries briefly, then acts normal
By Age
0-3 months
Normal: Babies this age cannot roll independently at first. The skull is soft with open fontanelles and is more vulnerable to injury. Scalp bruises can look dramatic due to rich blood supply.
Worry if: Any fall or head impact in this age group warrants medical evaluation. Look for bulging fontanelle, excessive sleepiness, persistent vomiting, seizures, or change in feeding behavior.
3-12 months
Normal: Babies start rolling and crawling; minor head bumps are very common. A brief cry followed by returning to normal activity is reassuring. Small bump or bruise (goose egg) at impact site is normal.
Worry if: Loss of consciousness (even briefly), vomiting more than twice, unusual drowsiness, unequal pupils, blood or fluid from ears or nose, bulging fontanelle, or inconsolable crying for more than an hour.
1-3 years
Normal: Toddlers fall frequently while learning to walk. Most result in minor bumps. A period of crying followed by return to normal behavior is reassuring.
Worry if: Confusion or disorientation, difficulty walking or coordination changes, severe headache (inconsolable crying), repeated vomiting, blood or clear fluid from ears/nose, or worsening symptoms over 24-72 hours.
Home Care
- Apply a cold compress or ice wrapped in a cloth for 20 minutes to reduce swelling
- Observe closely for at least 24-48 hours after any head injury
- Allow the child to sleep but wake every 2-3 hours the first night to check responsiveness
- Offer comfort and normal feeding; refusal to eat may be a warning sign
- Use acetaminophen (Tylenol) for pain relief if needed (not ibuprofen in the first 24 hours, as it may increase bleeding risk)
- Keep the child from vigorous activity for 24 hours
- Do NOT shake, jostle, or pick up the baby by their arms after a head injury
- Document what happened, the height of the fall, the surface landed on, and symptoms

Bottom line
Most cases of head injury in babies are not emergencies. However, seek immediate care if loss of consciousness, even briefly.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
