Worry is a reason to check, not a diagnosis — only a clinician can confirm.","answer_md":"*If your baby isn't moving or holding their head the way you expected, that worry deserves a clear, calm answer — not a scary checklist.*\n\n## In short\nAt 3–6 months, [Cerebral Palsy](/cerebral-palsy) (CP) is not something you diagnose at home — but it *is* an age where a few movement patterns are worth gently watching and mentioning to your doctor. The strongest reasons to check early are: persistently **stiff or floppy** muscle tone, **strong hand preference before 12 months**, poor head control, or movements that feel one-sided. Worry is a perfectly good reason to ask for a developmental check — it is not, by itself, a diagnosis.\n\n## What's worth watching at 3–6 months\nMost babies vary a lot, so look for *patterns that persist*, not single off days:\n\n- **Head control** — head still floppy or lagging well past 4 months when gently pulled to sit.\n- **Tone** — body feels very stiff (legs crossing/scissoring, arching) or very floppy like a rag doll.\n- **Asymmetry** — consistently using one hand or one side of the body far more than the other.\n- **Hands** — fists kept tightly clenched most of the time past 3–4 months, not reaching for toys by ~4–5 months.\n- **Feeding** — ongoing difficulty sucking, swallowing or frequent tongue-thrusting.\n\n## The science, briefly\nCP (WHO ICD-11 **8D20**) describes a group of movement and posture conditions arising from early, non-progressive changes in the developing brain. The reassuring part: signs at this age are *soft and watchful*, and tools used by clinicians — like the General Movements Assessment — can flag risk early, when the infant brain is most adaptable. Earlier support means better motor and functional outcomes.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online form. Our team reviews your baby's movement, tone and posture 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) and play-based motor support. The goal is always your child moving, exploring and thriving.\n\n## Trusted sources\nWHO ICD-11 (8D20); CDC \"Learn the Signs. Act Early.\" milestones; Indian Academy of Pediatrics; American Academy of Pediatrics (HealthyChildren.org).\n\n**Next step —** The kindest thing to do with worry is to check.
