The short answer
Running, jumping and climbing increase quickly at 31–36 months, while judging danger is still developing. Focus on high-consequence hazards such as windows, balconies, stairs, unstable furniture and slippery or cluttered routes.

Keep in mind
- Recheck windows, balconies, stairs and furniture as your child’s skills change.
- Use safe spaces for movement instead of trying to stop all exploration.
- After a head injury, watch for danger signs such as repeated vomiting, seizure or difficulty waking.
Why do fall risks change at this age?
A child nearing 3 may run faster, try two-footed jumps, open doors and move objects to reach new places. A window handle, shelf or worktop that was out of reach a few months ago may now be accessible. Recheck the home as new skills appear.
Small trips can be part of learning to move; the goal is not to stop all exploration. Offer safe chances to practise balance while physically blocking hazards where a fall could cause serious injury.
Which places at home should you check at child height?
Get down low and look for loose rugs, cords, toys and wet floors along walking routes. Keep stairs clear and check that safety gates are suitable and securely fitted.
Anchor dressers, bookcases and TVs. Use restraints on high chairs and changing surfaces, and never leave your child unattended on an elevated surface.
How can you make windows and balconies safer?
A fly screen is not a fall-prevention barrier. Use an appropriate window restrictor or guard and check that it works; choose one that does not block required emergency exit.
Move beds, sofas, tables and chairs away from windows and balcony rails. Supervise on balconies and check for gaps or horizontal parts that can be climbed.
How can you support movement safely?
Offer a safe alternative instead of only saying “don’t climb.” Stay close in age-appropriate play spaces with stable equipment and a suitable soft landing area.
Try stepping over cushions, walking along a line, stop-and-go music games or a soft ball. Avoid running in socks on slippery floors.
What should you check after a fall?
Check whether your child responds normally, is breathing normally and has severe bleeding or an obvious deformity. After a head bump, note when it happened and watch for changes; returning to play does not rule out later symptoms.
Inability to use or bear weight on a limb, increasing swelling, deformity or severe ongoing pain needs assessment. After a head injury, seek emergency care for confusion, seizure, repeated vomiting, increasing sleepiness or difficulty waking.
What can you do today?
Check windows, balconies, stairs and tall furniture from your child’s height.
Move chairs and boxes away from climbable hazards and retighten safety fittings.
Agree with other caregivers which signs after a fall require emergency help and how to note the time and what happened.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Call 911 for loss of consciousness, seizure, repeated vomiting, worsening confusion, inability to wake or severe breathing difficulty after a head injury.
- Seek medical advice for inability to use a limb, deformity, increasing swelling or persistent severe pain.
