YOUR QUESTION. A CLEARER NEXT STEP.
When to escalate if a child cannot run at the expected age
Most children run by 18–24 months. A frontline health worker should escalate for a developmental check if a child is not running by 24 months, not walking by 18 months, has lost a skill once present, or shows asymmetry, stiffness, floppiness, or accompanying speech and social delays. A single missed milestone in a thriving child may need only a 4–6 week follow-up; clustered flags or any skill loss warrant prompt referral. This is a referral decision, not a diagnosis.
In this answer 5 sections
A frontline worker who notices a child not yet running has spotted something quietly important — and knowing when to act is exactly the right instinct.
In short
Most children are running by around 18–24 months, with a comfortable, sure-footed run by about 2 to 2.5 years. As an ASHA or PHC worker, escalate for a developmental check when a child is not running by 24 months, when running was present and is now lost, or when the delay travels with other red flags — not walking by 18 months, frequent falls, stiff or floppy legs, or no words and little social connection. This is a referral decision, not a diagnosis — early review opens early support.
What to watch and when to escalate
Use a simple, calm threshold rather than waiting and watching indefinitely:
- By 18 months — child not yet walking independently: refer now.
- By 24 months — child walking but not attempting to run, or running looks very stiff, very floppy, or constantly off-balance: refer for a developmental check.
- Any age — loss of a skill the child once had (was running, now cannot): refer promptly.
- Asymmetry — one leg dragged, favoured or stiffer than the other; toe-walking that persists: refer.
- Travelling flags — not responding to name, very few words, poor eye contact, or marked muscle stiffness/floppiness alongside the motor delay: refer and note for clinician review.
A single missed milestone in an otherwise thriving, well-connected toddler may simply need a follow-up in 4–6 weeks; clustered flags or any skill loss should be escalated without delay.
The science
Running (ICF d4, mobility) builds on balance, leg strength and coordinated walking. Variation in timing is normal, but persistent gross-motor delay can be an early window into cerebral palsy, low muscle tone, or broader developmental delay — all of which respond best to early intervention. The frontline worker's role is to recognise the threshold and route, not to label.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a checklist in the field. Our clinicians assess how the child moves, balances and connects, then shape play-based support. Learn more about running and gross-motor milestones and how our physiotherapy team strengthens early movement.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Escalate if a child is not walking by 18 months, not running by 24 months, has lost a skill once present, shows asymmetry (one leg dragged or stiffer), persistent toe-walking, or marked stiffness/floppiness. Refer promptly when motor delay travels with no response to name, very few words or poor eye contact. A single missed milestone in a thriving toddler may need only a 4–6 week follow-up.
In everyday life
Keep a short note of what the child can do — walking, climbing, attempting to run — and whether one side moves differently from the other. A simple field note of how the child moves gives the clinician a clear starting picture.

Bring your questions to a first visitQuestions families ask
At what age should most children be able to run?
Most children begin running around 18–24 months and show a more sure-footed, coordinated run by about 2 to 2.5 years. Wide variation is normal, but not running at all by 24 months deserves a developmental check.
Should I escalate every child who is slightly late to run?
Not necessarily. A single missed milestone in a child who is otherwise walking well, connecting socially and developing language may simply need a follow-up in 4–6 weeks. Escalate promptly when the delay is clustered with other flags or when a skill has been lost.
What signs alongside not running need urgent referral?
Loss of a skill once present, one leg dragged or markedly stiffer, persistent toe-walking, marked muscle stiffness or floppiness, or motor delay alongside no response to name and very few words — these warrant prompt referral for clinician review.
