Gross Motor Delay
How Gross Motor Delay Is Assessed in Children Under 7
Gross motor delay in children under 7 is assessed by observing big-muscle milestones — sitting, crawling, walking, balance — alongside muscle tone, strength and coordination, using parent history and structured, play-based clinical observation. A clinical AbilityScore® is formed only at a Pinnacle centre under clinician care.
Before a child runs and jumps, they roll, sit, crawl and stand — and a careful look at those milestones tells us so much.
In short
Gross motor delay in children under 7 is assessed by watching how your child uses the big muscles for sitting, crawling, standing, walking, running, jumping and balance — and comparing that against expected milestones for their age. A clinician combines your own history of how your child moves at home with hands-on observation of posture, muscle tone, strength and coordination, often using a structured, validated movement assessment. The aim is never to label, but to see clearly where your child is today and what support will help most.What assessment actually looks at
A developmental physiotherapist or paediatric clinician will typically observe:- Milestone timing — head control, sitting, crawling, pulling to stand, walking, climbing stairs, hopping, against age-typical ranges.
- Muscle tone and strength — whether the body feels floppy or stiff, and how steadily your child holds a position.
- Posture, balance and coordination — how smoothly your child moves, turns and recovers from a wobble.
- Reflexes and symmetry — whether both sides of the body work evenly.
- Functional play — watching your child move naturally during everyday tasks rather than on command.
For children under 7 this is gentle, play-based and unhurried. There is no pass or fail — only a clear picture of your child's starting point.
The Pinnacle way
A clinical AbilityScore® — and any diagnosis — is formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an online form or app. Our clinicians map your child's gross motor delay profile and design a physiotherapy plan around real, everyday goals.Trusted sources

What to watch
Watch whether your child reaches movement milestones in a steady sequence — head control, sitting, crawling, walking — and whether both sides of the body move evenly. Persistent floppiness, stiffness or marked delay against age ranges is worth a gentle clinical check.
Try this at home
Give your child plenty of floor time and safe space to move, climb and explore. Movement is practice — the more chances to roll, reach and balance during play, the more those big muscles strengthen naturally.

Frequently asked
At what age should I worry about gross motor delay?
Milestones come in ranges, not exact dates. If your child is clearly behind expected ranges — for example not sitting by 9 months or not walking by 18 months — or if you notice floppiness, stiffness or uneven movement, a developmental check is worthwhile. Persistent parental concern is itself a good reason to ask.
Is the assessment uncomfortable for my child?
No. For children under 7 it is gentle, play-based and unhurried. The clinician watches your child move naturally through everyday tasks rather than testing them, so most children simply experience it as play.
Does a delay mean my child has a lasting problem?
Not at all. An assessment shows where your child stands today, not their future. Many gross motor delays respond very well to early, targeted physiotherapy support — which is exactly why early assessment matters.
