YOUR QUESTION. A CLEARER NEXT STEP.
My child can't climb stairs — should I be worried?
Stair-climbing develops across a wide, normal range — many toddlers climb with support around 14–18 months and more independently between 2 and 3 years, so a child not yet climbing is often still developing. A gentle check helps if climbing is far behind peers, if walking or balance also struggle, or if a skill has faded. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

When little legs aren't quite climbing yet, it usually means a skill is still building — and most of the time, with the right play and patience, it comes.
In short
Stair-climbing is a gross-motor skill that develops over a wide, normal range — many children begin pulling up steps with support around 14–18 months and manage stairs more independently between 2 and 3 years. So a toddler who isn't climbing yet is often simply still developing. It's worth a gentle check, though, if climbing seems much harder than for peers, if your child also struggles with walking, balance or standing up, or if a skill they once had seems to have faded. Most children make steady progress with practice — and where extra support helps, it works beautifully.
What's actually involved in climbing stairs
Climbing a step is a surprisingly big job for a small body — it asks for leg strength, balance, the confidence to shift weight onto one foot, and the motor planning to sequence the movement. Children build these blocks at different paces:
- Strength and balance grow through everyday play — squatting, standing, walking on uneven ground.
- Confidence matters as much as ability; some children are simply more cautious and need familiar, safe practice.
- Opportunity counts too — a child who rarely meets stairs has had less chance to learn them.
When a gentle check helps
A developmental check is worth booking if your child:
- is markedly behind same-age peers in climbing, walking or standing up from the floor,
- seems unusually stiff, floppy, or strongly favours one side of the body,
- tires very quickly or appears in discomfort when moving,
- or has lost a movement skill they previously had — this last one always warrants prompt attention.
These signs simply help a clinician tell apart "still developing" from "could use a little support" — and the earlier that's clear, the gentler the path forward.

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or an online form. If you'd like reassurance, a clinician can build a precise developmental profile and, where useful, shape a playful movement plan through our occupational therapy programme.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch whether your child is steadily building strength and balance — squatting, standing, walking on uneven ground. A check is worth booking if climbing is much harder than for peers, if walking or balance also struggle, if movement seems stiff or floppy, or if a skill once present has faded.
In everyday life
Make stairs into safe, supported play — hold a hand, count each step aloud, and let your child practise low steps or cushions. Squatting games, climbing over sofa cushions and walking on uneven ground all build the strength and confidence stairs need.

Bring your questions to a first visitQuestions families ask
At what age should my child climb stairs?
Climbing develops over a wide, normal range. Many children begin going up steps with support or holding a hand around 14–18 months, and manage stairs more independently somewhere between 2 and 3 years. Children vary a great deal, so being a little later than another child is usually not a concern on its own.
My toddler isn't climbing yet — is that a delay?
Often not. Many toddlers are simply still building leg strength, balance and confidence, or have had little chance to practise on stairs. It's worth a gentle check if climbing is far behind peers, or if walking, standing up or balance also seem hard.
When should I genuinely worry?
Seek a check promptly if your child seems unusually stiff or floppy, strongly favours one side, tires very quickly when moving, or has lost a movement skill they previously had. These help a clinician tell apart normal development from a need for support.
How can I help my child learn to climb stairs?
Practise safely with a hand to hold and one step at a time, count steps aloud to make it fun, and build strength through everyday play — squatting, walking on uneven ground and climbing over cushions all help.
