When to escalate if a child isn't jumping at the expected age

A child who isn't yet jumping is rarely an emergency — but knowing exactly when to act turns a frontline visit into early, life-changing support.

In short

Most children begin a two-footed jump in place between roughly 24 and 36 months. If a child is past their second birthday and not yet attempting to leave the ground with both feet, treat it as a prompt to observe and refer for a developmental check — not as a diagnosis. Escalate to the PHC medical officer or developmental clinic when the gap is clear, when it travels with other motor or communication delays, or when a parent is worried.

When to escalate at the PHC

Jumping is a gross-motor milestone (ICF d4, mobility). As a frontline worker, escalate when you see:

• No two-footed jump attempt by ~30 months, or no clear jump by 36 months.
• Several skills lagging together — not running steadily, not climbing stairs, not kicking a ball, alongside the jumping gap.
• Loss of a skill the child once had, or floppy or very stiff muscle tone.
• Frequent falls, marked clumsiness, or favouring one side of the body.
• Delays beyond motor — few words, no pointing, little eye contact or response to name.
• Parent concern, which is itself a strong reason to refer.

If any single skill suggests a medical cause — sudden weakness, regression, or stiffness — escalate promptly to the medical officer, not therapy-first.

The science

Jumping needs leg strength, balance, and the coordination to push off and land with both feet. It typically follows running and stair-climbing. A short delay in one isolated skill is often a normal variation; what matters for escalation is the pattern — several flags together, or a delay that persists past the expected window.

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 look at the whole picture of how a child moves, plays and communicates. You can read more about jumping and how our occupational therapy team supports gross-motor development.

Next step — Don't wait on a clear or persistent gap. Book a developmental assessment for the child, and note what the family has observed at home.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
