Is My 6-to-9-Month-Old Developing Normally in Motor Skills?

Watching your baby reach, roll and sit — and wondering if it's all on track — is one of the most natural parts of loving them.

In short

Between 6 and 9 months, most babies are busy learning to sit, roll both ways, reach for toys and pass them hand to hand. There is a wide, healthy range here — some babies sit steadily at 6 months, others closer to 9, and both can be perfectly typical. A gentle developmental check is wise if your baby isn't beginning to sit with support, isn't reaching for things, feels very stiff or very floppy, or only ever uses one side of the body. This is reassurance and information — not a diagnosis.

What to watch at 6–9 months

Motor skills bloom on a spectrum, not a fixed timetable. Many babies in this window are starting to:

• Sit — first with hands propped, then steadily on their own as the months go by.
• Roll both ways, and push up on their arms during tummy time.
• Reach and grasp — stretching for toys, holding them, and passing an object from one hand to the other.
• Bear some weight on their legs when held standing, and begin to bounce.

Gentle flags that deserve a clinician's calm look include:

• No sitting with support beginning to emerge by around 9 months.
• Not reaching for or grasping toys.
• Stiffness or floppiness — limbs that feel very tight or unusually loose.
• One-sided use — strongly favouring one hand or one side, or not using one limb.
• Loss of a skill your baby previously had.

Remember that babies who spend lots of time on their tummies, and who have room to explore, often build these skills sooner — and a slightly slower starter is very often simply finding their own pace.

When to act

If your baby isn't beginning to sit with support, isn't reaching for objects, feels markedly stiff or floppy, or uses only one side of the body, arrange a developmental check now rather than waiting. Your daily observations are valuable clinical information — trust them.

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 your baby moves, plays and explores, then shape gentle, play-led support around their strengths. Our occupational therapy team can guide tummy time, reaching and sitting play, and you can always begin with a simple developmental check.
