Cerebral Palsy can often be identified between 12 and 18 months, and earlier in higher-risk babies, by combining observation of movement, muscle tone and posture with developmental history and sometimes MRI. A single sign is not a diagnosis. AbilityScore® is a clinician-administered structured assessment, and any diagnosis is formed only at a Pinnacle Blooms Network centre under qualified clinician care.

*Yes — and noticing the early signs now is one of the most hopeful things you can do, because the developing toddler brain responds beautifully to early support.*

## In short
Yes, **Cerebral Palsy (CP)** can often be identified between **12 and 18 months**, and in higher-risk babies (for example, those born very preterm) clinicians can flag it even earlier. A confident diagnosis usually rests on a careful look at how your child moves, their muscle tone and posture, their developmental history, and sometimes a brain scan (MRI). If you have any worry about how your toddler moves, sits, crawls or uses their hands, please ask for a developmental review — early action makes a real difference.

## What clinicians look at in the 12–18 month window
CP is a difference in how the developing brain controls movement and posture. By this age, doctors and therapists watch for patterns rather than a single sign:

- **Movement & milestones** — not yet sitting steadily, not pulling to stand, or delayed crawling; movements that look stiff or unusually floppy.
- **Muscle tone** — limbs that feel very tight (stiff) or very loose, or stiffness that changes with movement.
- **Hand use** — a strong, early preference for one hand before 18 months (most babies use both fairly equally until later).
- **Posture & reflexes** — asymmetry (one side used much more than the other), persistent fisting, or tip-toe positioning when held to stand.
- **History** — prematurity, birth complications, or newborn brain-imaging findings raise the index of suspicion.

A single observation is not a diagnosis. Clinicians combine standardised tools — such as the General Movements Assessment and the HINE neurological exam — with history and, where needed, an MRI, to build a clear picture.

## Why earlier is genuinely better
A toddler's brain is wonderfully adaptable. Identifying CP early opens the door to physiotherapy, occupational therapy and family-guided practice during a window when new pathways form most readily. Early support protects movement, communication, feeding and play — and equips you with everyday strategies that help your child thrive at home.

## The Pinnacle way
This is general information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician. Our AbilityScore® is a clinician-administered structured assessment that maps your child's movement, communication and daily skills against their own baseline, so support can be tailored and re-measured over time. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our team turns findings into practical, everyday help.

## Trusted sources
The CDC and HealthyChildren (AAP) describe early movement milestones and the value of acting early on motor concerns; WHO's ICD-11 classifies cerebral palsy; international consensus supports early detection using tools such as the General Movements Assessment and HINE alongside MRI.
