Cerebral Palsy
When to Worry About Cerebral Palsy at 6–9 Months
Between 6 and 9 months, watch how your baby moves rather than one milestone: persistent stiffness or floppiness, strong one-sidedness, fisted hands, poor head control or no rolling are worth a gentle check. A pattern that persists is the real flag — and early assessment is hopeful, not frightening. Only a Pinnacle clinician can confirm anything.
If your baby isn't moving or rolling quite the way you hoped, that worry is real — and it deserves a clear, calm answer.
In short
Cerebral palsy (CP) is a difference in how the developing brain controls movement and posture. Between 6 and 9 months, the most useful signals are about how your baby moves — not a single missed milestone. Worth a gentle check if you notice:- Stiffness or floppiness — limbs that feel very tight or unusually limp when you lift or dress your baby
- Strong one-sidedness — consistently reaching, rolling or kicking with only one hand or leg, or a fisted hand that won't open past around 4–5 months
- Not rolling or no head control — head still lagging, or no rolling by about 6–7 months
- Stiff, scissoring or crossing legs, or pushing back arched when held
- Feeding difficulty — persistent trouble sucking, swallowing or frequent gagging
One quiet week, or a baby who simply takes their own time, is usually nothing. A persistent pattern that you see day after day is the real reason to check — and checking early is the most hopeful thing you can do.
The science, briefly
CP (WHO ICD-11 8D20) arises from an early, non-progressive event affecting the developing brain. The signs aren't always present at birth — they often emerge as movement and posture develop across the first year, which is exactly why 6–9 months is a meaningful window to observe. Spotting concerns early matters enormously: the infant brain is at its most adaptable, so early movement-focused support builds the strongest foundations.The Pinnacle way
An online list can never confirm or rule out CP — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care. Our team measures your baby against their own baseline, looks for other explanations first, and shapes a plan around play, posture and movement through occupational therapy — clarity and a path, never a label from a form.Trusted sources

What to watch
Seek a check sooner if your baby loses a skill they once had, has a hand that stays tightly fisted, consistently uses only one side of the body, or shows persistent feeding, swallowing or breathing difficulty.
Try this at home
Give your baby short, daily supervised tummy-time play. Place a favourite toy slightly to each side in turn to encourage reaching and rolling with both hands — and notice whether both sides join in equally.

Frequently asked
Can cerebral palsy be diagnosed at 6 months?
Often it cannot be confirmed this early, but clear concerns about movement, stiffness, floppiness or strong one-sidedness can and should be assessed now. Early observation by a qualified clinician guides timely support — a definite diagnosis may come a little later.
Is it normal for my baby to favour one hand at this age?
A clear, consistent hand preference before about 12 months is unusual and worth checking. Most babies at 6–9 months reach and explore with both hands fairly equally, so persistent one-sidedness is a gentle flag for a developmental review.
My baby hasn't rolled yet — should I worry?
Not on its own. Babies vary, and one missed week means little. Combine it with other signs — poor head control, stiffness or floppiness — or a pattern that persists past 6–7 months, and a calm check with a clinician is sensible.
