Worry is reasonable, but worry is not a diagnosis. Between 9 and 12 months, watch how your baby moves — stiff or floppy limbs, favouring one side, not sitting, or a fisted hand. A persistent pattern is the cue to check promptly; only a clinician can confirm.

*If your baby isn't moving the way you expected, the worry is real — and there is something useful you can do with it.*

## In short
Worry is reasonable, but worry is not a diagnosis. Between 9 and 12 months, the signs worth attention with [Cerebral Palsy](/cerebral-palsy) are about *how* your baby moves, not just *when*. Flags include: not sitting steadily on their own, stiff or floppy limbs, using only one hand or side while the other stays fisted, no rolling or attempt to crawl, or difficulty bearing weight on the legs. A single late milestone is common; a *persistent pattern* of these signs is the real reason to have your baby checked promptly.

## What to watch
- **Posture and tone** — limbs that feel very stiff or unusually limp; a back that arches strongly
- **Asymmetry** — clearly favouring one hand or side, or a hand staying fisted past 6–7 months
- **Motor milestones** — not sitting with support by ~9 months, no rolling, no pushing up on arms
- **Feeding** — ongoing difficulty with swallowing or excessive drooling

If you see a steady pattern — not a single off day — that is the cue to act.

## The science, briefly
Cerebral Palsy (WHO ICD-11 **8D20**) describes a group of movement and posture differences from early brain development. The hopeful truth: it can often be flagged in infancy, and the infant brain's plasticity means **early therapy works best in the first years**. Identifying motor concerns early — rather than waiting — is now the global standard, because timely occupational and movement therapy can meaningfully shape function and independence.

## The Pinnacle way
Only a qualified clinician at a Pinnacle Blooms Network centre can tell whether this is Cerebral Palsy or a passing variation — a clinical AbilityScore® and any diagnosis are formed only there, under qualified care, never from an online form. Our team measures your baby against their *own* [AbilityScore baseline](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and, where helpful, begins gentle [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) to build movement, strength and everyday skills.
