YOUR QUESTION. A CLEARER NEXT STEP.
When should I be concerned about my child's motor development?
Most children reach motor milestones across a wide, healthy range, so small variations are usually fine. Seek a developmental check if your child misses several milestones, loses a skill once gained, strongly favours one side of the body, or feels persistently very stiff or very floppy. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

Every child rolls, sits, stands and runs to their own rhythm — but knowing the gentle signposts helps you act early when it matters.
In short
Most children reach motor milestones across a wide, healthy range — so a few weeks' variation is usually nothing to worry about. It is worth a check if your child misses several milestones for their age, loses a skill they once had, uses one side of the body far more than the other, or feels persistently very stiff or very floppy. Early support is gentle and effective, and seeking a check never means something is wrong — it simply means you get clarity and a plan.
Signs worth a closer look
Motor development covers both gross motor skills (rolling, sitting, crawling, walking, jumping) and fine motor skills (grasping, pointing, stacking, holding a crayon). Consider a developmental check if you notice:
- By around 4 months — not bringing hands together, not pushing up or holding the head steady, or seeming very floppy or very stiff.
- By around 9 months — not sitting with support, not bearing weight on the legs, or not reaching for and grasping toys.
- By around 12–18 months — not pulling to stand, not taking steps, or strongly favouring one hand before this age (which can mean the other side is being missed).
- By around 2 years — not walking steadily, frequent falling, or unable to manage steps with help.
- At any age — losing skills they once had, persistent stiffness or floppiness, walking only on tiptoes, or a clear and lasting difference between the two sides of the body.
A single late milestone in an otherwise thriving child is often just their own pace. A pattern of delays, a loss of skills, or a marked asymmetry is the signal to check.
When to refer
Book a developmental check if you recognise a cluster of the above, if a milestone is well behind the expected window, or if your instinct simply tells you something has changed. Loss of a previously gained skill, sudden weakness, or marked stiffness needs prompt medical review rather than a wait-and-watch approach. Trusting your observations is always reasonable — you know your child best.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online checklist. With 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, our team builds a clear developmental profile and, where helpful, a gentle plan through occupational and physiotherapy support.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for a pattern of missed gross or fine motor milestones, loss of a skill once gained, strong favouring of one side before 18 months, persistent stiffness or floppiness, or tiptoe walking — and trust your instinct if something has changed.
In everyday life
Give your child plenty of safe floor and play time each day — reaching for toys, crawling, climbing and scribbling all build motor skills naturally, and let you notice how both sides of the body are working.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is it normal for my child to reach motor milestones a little late?
Yes — milestones span a wide, healthy range, and many thriving children reach one or two a few weeks later than average. What matters more is a pattern of several delays, a loss of a skill once gained, or a clear difference between the two sides of the body.
My child strongly prefers one hand as a baby — is that good?
A strong hand preference before about 18 months is worth a check, because it can mean the other side is being used less than expected. Most children develop a clear dominant hand later, in the toddler and preschool years.
What is the difference between gross and fine motor skills?
Gross motor skills use the large muscles — rolling, sitting, crawling, walking and jumping. Fine motor skills use the small muscles of the hands and fingers — grasping, pointing, stacking and holding a crayon. A developmental check looks at both.
Does seeking a check mean something is wrong?
Not at all. A check simply gives you clarity and, if needed, an early plan. Early support is gentle and effective, and many concerns turn out to be a child's own healthy pace.
