Early Signs of Cerebral Palsy in a 1-Year-Old Boy

When a little one seems to move differently from other babies their age, a watchful parent's eye is often the very first step towards timely help.

In short

In a 1-year-old, early signs of Cerebral Palsy (ICD-11 8D20) usually show up as differences in movement, muscle tone and posture — a baby who feels unusually stiff or floppy, strongly favours one hand or side, or is delayed in sitting, crawling or pulling to stand. These are signs worth checking, not a diagnosis. Many causes of early movement differences are treatable, and the earlier they are looked at, the better.

Early signs to watch in a 1-year-old boy

Muscle tone and posture

• Feels stiff (limbs hard to bend or move) or unusually floppy when held
• Stiff or scissoring legs, or persistently arched back
• Awkward, asymmetric posture when sitting or lying

Movement and motor milestones

• Not sitting steadily without support by around 9–12 months
• Not bearing weight on the legs, or pushing up stiffly on tiptoes
• Delayed crawling, or crawling in a lopsided way (one side dragging)
• Hands kept fisted, or strong hand preference before 12–18 months (favouring one side this early can signal weakness on the other)

Feeding and everyday cues

• Difficulty with feeding, sucking or swallowing; frequent drooling
• Trouble bringing both hands to the middle, or to the mouth

A single sign on its own is rarely cause for alarm — babies develop at different paces. A pattern of these signs, or your steady gut feeling that something is different, is reason enough to ask for a check.

When to seek a check

Don't wait and watch alone. Speak to your paediatrician promptly if you notice persistent stiffness or floppiness, strong early hand preference, or movement milestones that aren't arriving. Cerebral Palsy is a difference in how the developing brain controls movement — and early support through physiotherapy and occupational therapy can make a real difference to how your child moves, plays and grows.
