YOUR QUESTION. A CLEARER NEXT STEP.
If a child isn't yet showing gross motor skills
Gross motor skills are big movements like sitting, crawling and walking. If a child isn't showing the movements expected for their age, arrange a calm developmental check rather than waiting. Watch for not steadying the head by ~4 months, not sitting independently by 9 months, not crawling by ~12 months, or not walking by 18 months, plus very stiff or floppy muscles or loss of a skill. This is not a diagnosis — early support works best.

Every child finds their feet on their own timeline — noticing where your little one is right now is loving, attentive caregiving.
In short
Gross motor skills are the big movements — holding the head up, rolling, sitting, crawling, pulling to stand and walking. If a child in your care isn't yet showing the movements you'd expect for their age, the kindest, most useful step is a calm developmental check rather than waiting and worrying. This isn't a diagnosis — children develop at different paces, and an early, gentle look turns small questions into early opportunities, where support works beautifully.
What to watch
Gross motor (ICF domain d4) unfolds in a broad but recognisable sequence. Gentle flags that deserve a clinician's eye:
- Head control — not steadying the head by around 4 months.
- Sitting — not sitting with support by 6–7 months, or independently by 9 months.
- Moving — no crawling, scooting or bottom-shuffling by around 10–12 months.
- Standing and walking — not pulling to stand by 12 months, or not walking by 18 months.
- Other signs — very stiff or very floppy muscles, strongly favouring one side, or losing a movement once gained.
Trust what you notice every day — that observation is valuable information for a clinician.
The science
Gross motor progress reflects how the brain, muscles and balance systems work together. Movement is also the foundation for play, exploration and learning, which is why an early, supportive look matters. Floor time, tummy time, reaching games and safe space to move all help — but if milestones are clearly behind, a structured review is the right next step.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online list. Our clinicians watch how a child moves, sits and balances, and build support around play. Learn more about gross motor development and how our physiotherapy team helps build strength, balance and confidence.

Next step — Trust what you've noticed. Book a developmental assessment with a Pinnacle clinician for a calm, clear review of the child's movement and milestones.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a check if a child isn't steadying the head by ~4 months, sitting independently by 9 months, crawling or moving by ~12 months, or walking by 18 months. Also watch for very stiff or very floppy muscles, strongly favouring one side, or losing a movement once gained.
In everyday life
Make daily floor and tummy time playful — place a favourite toy just out of reach to invite reaching, rolling and crawling. Note in a phone diary which movements you see and when, so a clinician has a clear picture.
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
At what age should a child be walking?
Most children walk between 12 and 18 months, but the range is wide. If a child isn't walking by 18 months, or isn't pulling to stand by 12 months, a calm developmental check is wise — not as a diagnosis, but so support can start early if needed.
Is it normal for children to crawl at different ages?
Yes. Some children crawl, some bottom-shuffle, and a few skip crawling altogether. What matters more is steady progress in moving, sitting and standing. If there's no way of getting around by about 12 months, mention it to a clinician.
Will my child catch up on their own?
Many children simply move at their own pace and do catch up. But because early movement supports play and learning, a gentle clinician's look is the safest way to tell whether a child needs a little extra support or just more time.
