Motor milestones for a 6-to-9-month-old
Between 6 and 9 months most babies learn to sit without support, roll both ways, push up on their arms, pass toys hand to hand, and begin to scoot, rock or crawl. Milestones come in a range, not on a fixed date. If a baby isn't sitting with support or bearing weight on their legs by 9 months, a friendly developmental check is worthwhile.
In this answer 5 sections
Around the half-year mark, your baby's whole body is preparing for one big adventure — moving away from you, just a little, and looking back to make sure you're still there.
In short
Between 6 and 9 months most babies learn to sit without support, roll both ways, push up on their arms, pass a toy from one hand to the other, and begin to scoot, rock on hands and knees or crawl. Milestones arrive in a range, not on a fixed date — a baby born early may reach them a little later. If your little one isn't sitting with support or bearing weight on their legs by 9 months, it's simply worth a friendly developmental check.
What to look for from 6 to 9 months
Big movements (gross motor)
- Sits without support, hands free to play (often by 8–9 months)
- Rolls both ways — tummy to back and back to tummy
- Pushes up on straight arms during tummy time; holds head steady
- Bears weight on legs and may bounce when held standing
- Begins to rock on hands and knees, scoot, or move towards a toy just out of reach
Hand and finger skills (fine motor)
- Reaches for and grasps toys, brings them to the mouth
- Passes an object from one hand to the other
- Rakes small objects towards the palm; a finer pincer grasp emerges nearer 9–10 months
- Bangs two toys together and holds a bottle or finger food
A gentle word on range
Development is a wide, healthy band — siblings differ, and adjusted age matters for premature babies. Steady forward progress over weeks tells you far more than hitting any single date. What deserves a check rather than a wait is no movement forward: not sitting with help, not bearing weight on legs, not reaching for things, or a loss of a skill already gained by 9 months.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of qualified clinicians — never from an online list. If you'd like reassurance, our team can map your baby's movement across domains and show you simple, playful next steps at home. Explore a developmental check, our occupational therapy for early motor skills, and how the AbilityScore® gives an objective, multi-domain baseline.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Worth a check rather than a wait: not sitting with support, not bearing weight on legs, not reaching for objects, or losing a skill already gained by 9 months. Use adjusted age for babies born early.
In everyday life
Give supervised floor and tummy time daily, and place a favourite toy just out of reach — it gently invites your baby to pivot, scoot and eventually crawl.
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
Should my 6-to-9-month-old be crawling yet?
Not necessarily. Many babies begin rocking on hands and knees, scooting or commando-crawling in this window, while others crawl later or skip it entirely and move straight to pulling up. Steady progress in moving towards a toy matters more than the exact style or date.
My baby isn't sitting alone at 8 months — should I worry?
Sitting without support often settles between 8 and 9 months, so a little later can still be within the healthy range. If your baby isn't sitting even with support or isn't bearing weight on their legs by 9 months, a gentle developmental check is sensible for reassurance.
Does prematurity affect these milestones?
Yes. For a baby born early, use adjusted age — counting from the due date rather than the birth date — until around two years. This gives a fairer picture of where their motor skills are expected to be.
