Bonk! My kid just hit their head…What do I do?”
Written by Dr. Ostrander
Who hasn’t had a moment when a friendly parent-child wrestling match ends in some tears because Dad “got a little carried away” stealing the village people (stuffed animals) from the castle, which was defended by the Fearless Princess?...Just me?
Whether it’s during some roughhousing, they’re launching off the couch with zero respect for gravity, accidentally running full speed into a wall, or colliding with a friend on a trampoline, head bumps are part of the job description of being a kid—and thus part of our job to know how to manage the tears afterward. But how do you know when it’s just a “bonk” that calls for a kiss and a Band-Aid or when it’s something that needs a bit more attention?
Here’s a quick guide for you, fearless guardian, because let’s be honest: these things happen!
When to Call your Healthcare Provider or Head (pun intended) to the ER:
If your child hits their head and you notice any of the following, it’s time to stop Googling and start dialing:
Loss of consciousness (even briefly): If your kiddo passes out, they need to be checked out – ASAP.
Vomiting more than once: One puke could be nerves or shock. Multiple vomits? Call your pediatrician.
Severe headache that won’t go away: Especially if it's getting worse over time.
Unusual behavior: If your normally chatty 5-year-old suddenly turns into a quiet little statue, or seems confused or dazed, that’s a red flag.
Drowsiness or trouble waking up: Sure, kids nap, but if you can’t easily wake them or they seem “off,” it’s time to seek help.
Seizures
Blood or liquid draining from the ear
Weakness, slurred speech, or problems with balance or coordination
One pupil larger than the other: (This one sounds made up, but it’s not—and it's a biggie.)
And if your baby under 1 year hits their head, err on the side of caution and give us a callthey’re more fragile.
When to Chill (But Keep an Eye Out):
Many head bumps look worse than they are—hello, giant forehead goose egg! Here’s when you can likely skip the ER:
They cried immediately and calmed down after a few minutes
They’re acting like their usual self within 15–30 minutes
There’s a bump or bruise, but no change in behavior
They didn’t lose consciousness and they’re walking/talking/playing fine
Fun fact: the forehead is basically nature’s bumper. It bruises easily and dramatically, but it’s strong! So yes, your child may look like a unicorn for a day or two, but they’ll be fine. Magical, even.
What About Sleeping?
Old advice used to be “don’t let them fall asleep.” Good news: That’s a myth. According to the American Academy of Pediatrics (AAP), it’s OK to let your child sleep after a head injury—as long as they’re acting normally before bed. Just wake them up a couple times overnight to make sure they respond normally.
Concussion? What Does That Even Mean?
A concussion is a mild brain injury caused by a bump, blow, or jolt to the head. Symptoms can include:
Headache
Dizziness
Nausea
Trouble concentrating
Feeling “off”
Most kids recover fully with rest and some TLC—but they should avoid sports, screen time, and roughhousing until cleared by a provider.
Final Word from the Doc
You know your child best. If something “doesn’t feel right” trust your gut and give us a call! We’d always rather reassure you than have you second-guess yourself.
Also, “maybe once in awhile the Princess can actually save the villagers from the dragon and you don’t have to win, OK Dad?” or so I’m told.
