YOUR QUESTION. A CLEARER NEXT STEP.
When should I worry about my child's motor development?
Some variation in when children sit, crawl and walk is completely normal. Seek a gentle developmental check if your child misses a key motor milestone by a clear margin, loses a skill once had, shows strong hand-preference before age one, stays unusually stiff or floppy, or isn't progressing over several months. These are reasons to assess early — not a diagnosis — because early support works best.

Watching your little one reach, roll and toddle is one of parenting's quiet joys — and noticing when something feels off-pace is loving attention, not worry for its own sake.
In short
Children grow into their movement skills at their own pace, and a few weeks' variation is completely normal. The time to seek a gentle developmental check is when your child misses a key motor milestone by a clear margin, loses a skill they once had, has a strong side-preference before their first birthday, stays unusually stiff or floppy, or isn't moving forward over several months. None of this is a diagnosis — it simply means a clinician's calm look is wise now, because early support works beautifully.
What to watch by age
Motor development unfolds along two threads — big-body (gross motor) and small-hand (fine motor) skills. Gentle flags worth a clinician's eye include:
- By ~4 months — not holding the head steady, not pushing up on tummy, hands always tightly fisted.
- By ~9 months — not sitting with support, not bearing weight on legs, not reaching for or passing toys between hands.
- By ~12 months — not pulling to stand, not using a finger-and-thumb pincer grasp, and a strong, consistent preference for one hand (early hand-dominance can be a flag at this age).
- By ~18 months — not walking independently, not picking up small objects.
- By ~2 years — not climbing, not running, frequent falling.
- At any age — stiffness or floppiness in the limbs, a clear loss of a skill once mastered, or a body that consistently turns to one side.
The aim is never alarm — it's that an early, calm observation turns a small question into an early opportunity.
When to act
If your child has lost a skill, is markedly stiff or floppy, isn't progressing over a few months, or you simply have a steady parent instinct that something is different — arrange a developmental check now rather than waiting. What you observe every day is valuable clinical information.
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 team builds its own picture of your child's strengths and watches how they move, sit, reach and balance, shaping support around play. Our physiotherapy and occupational therapy teams help with strength, balance, posture and fine-motor skills, and you can explore more about us and how we work.

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

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a check if your child isn't holding head steady by ~4 months, not sitting by ~9 months, not pulling to stand by ~12 months, not walking by ~18 months; or shows strong one-side preference before age one, marked stiffness or floppiness, loss of a skill once had, or no progress over several months. Trust your parent instinct.
In everyday life
Keep a short phone note of what your child can do — head control, sitting, reaching, standing, walking — and the rough age each appeared. A simple timeline gives a clinician a clear, useful 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
Is it normal for my child to skip crawling?
Yes — some children bottom-shuffle, commando-crawl or move straight to standing and walking, and skip classic crawling entirely. What matters more is steady progress in head control, sitting, standing and walking. If your child isn't moving forward over several months, a gentle developmental check is wise.
My toddler walks on tiptoes — should I worry?
Occasional toe-walking is common as toddlers experiment with movement and usually settles. Seek a clinician's view if toe-walking is constant, your child can't bring heels to the floor, the legs feel stiff, or it comes alongside other developmental differences.
How much milestone variation is normal?
A few weeks either side of a typical age is completely normal — children are individuals. The flags to act on are a clear, sustained gap from a milestone, losing a skill once mastered, marked stiffness or floppiness, or no progress over months.
