For parents of newborns, every milestone feels monumental. But when developmental progress seems slower than expected, worry naturally follows. Understanding the early signs of cerebral palsy in newborns can help parents recognize potential concerns and seek timely medical evaluation. According to the Centers for Disease Control and Prevention (CDC), approximately 1 in 345 U.S. children has been diagnosed with cerebral palsy, making it the most common motor disability of childhood.
This guide provides comprehensive, parent-friendly information about recognizing the warning signs of cerebral palsy in infants, understanding when to seek medical advice, and learning what resources are available if medical negligence contributed to your child’s condition.
What Is Cerebral Palsy?
Cerebral palsy (CP) is a group of disorders that affect a person’s ability to move and maintain balance and posture. The National Institute of Child Health and Human Development (NICHD) explains that cerebral palsy is caused by abnormal brain development or damage to the developing brain that affects a child’s ability to control muscles.
The condition is permanent but non-progressive, meaning it doesn’t worsen over time. However, symptoms may become more apparent as a child grows and developmental milestones are expected. Cerebral palsy can range from mild (requiring minimal assistance) to severe (requiring comprehensive care and support).
Important to Know: Cerebral palsy is not always evident at birth. The NICHD reports that signs usually appear in the first few months of life, but many children are not diagnosed until age 2 or later when developmental delays become more pronounced.
Timeline of Early Signs by Age
Cerebral palsy signs often emerge gradually as babies grow. Here’s a month-by-month guide to help parents understand what to watch for at different developmental stages.
Birth to 3 Months
During the newborn period, subtle signs may include:
- Abnormal muscle tone: Baby feels unusually stiff (hypertonic) or floppy (hypotonic) when picked up
- Feeding difficulties: Problems with sucking, swallowing, or coordinating breathing during feeding
- Excessive crying or irritability: Persistent fussiness that doesn’t respond to typical soothing methods
- Head lag: Significant difficulty supporting head when pulled to sitting position after lying on back
- Poor reflexes: Absent or exaggerated reflexes such as the Moro (startle) reflex
3 to 6 Months
As babies develop more intentional movements, concerning signs may include:
- Delayed rolling: Not attempting to roll over by 4-6 months
- Hand preference too early: Consistently using one hand before 12 months (according to clinical guidelines published by NCBI, hand preference before age 1 should trigger further assessment)
- Stiff legs: Legs become rigid or cross (scissor) when picked up
- Arching back: Baby repeatedly overextends back and neck, seeming to push away when held
- Asymmetric movements: One side of the body moves differently than the other
6 to 12 Months
This period is critical for gross motor milestone achievement. Warning signs include:
- Not sitting independently by 8 months: Cannot sit without support past this age
- Inability to bring hands together: Doesn’t clap, grasp toys, or bring hands to mouth
- Crawling abnormalities: Drags one side of body, scoots on bottom instead of crawling, or doesn’t crawl at all
- Difficulty with reaching and grasping: Struggles to pick up objects or shows poor coordination
- Persistent toe walking: Stands only on toes, with stiff leg muscles
12 to 18 Months
By the toddler stage, developmental delays become more apparent:
- Not walking by 18 months: The NHS identifies this as a key red flag
- Walking on toes or with abnormal gait: Scissor gait, stiff movements, or asymmetric walking pattern
- Speech delays: Not saying single words or showing difficulty with mouth movements
- Fine motor skill delays: Trouble self-feeding, pointing, or manipulating small objects
Types of Cerebral Palsy and Their Specific Signs
Cerebral palsy is classified into several types based on the kind of movement problems present and which parts of the body are affected.
Spastic Cerebral Palsy
Most common type (approximately 80% of cases)
Primary signs:
- Increased muscle tone (stiffness)
- Jerky movements
- Tight muscles that don’t stretch easily
- Exaggerated reflexes
- Scissoring of legs when walking
Dyskinetic Cerebral Palsy
Characterized by involuntary movements
Primary signs:
- Slow, writhing movements (athetosis)
- Rapid, jerky movements (chorea)
- Muscle tone that changes (low to high)
- Difficulty with posture and sitting
- Problems with speaking and swallowing
Ataxic Cerebral Palsy
Least common type (5-10% of cases)
Primary signs:
- Poor balance and coordination
- Shaky movements or tremors
- Difficulty with precise movements
- Wide-based, unsteady walking
- Trouble with depth perception
Mixed Cerebral Palsy
Combination of multiple types
Primary signs:
- Symptoms from more than one type
- Most commonly spastic-dyskinetic
- Varying muscle tone in different body parts
- Complex movement patterns
- Multiple areas of the brain affected
Normal Development vs. Cerebral Palsy Signs
Understanding typical developmental milestones can help parents identify when delays warrant medical attention. This comparison table provides guidance based on NICHD developmental milestone research.
| Age | Typical Development | Potential CP Warning Signs |
|---|---|---|
| 2 Months | Lifts head while on tummy; begins to push up | Cannot lift head; head lags significantly when pulled to sit |
| 4 Months | Rolls from tummy to back; brings hands to mouth | No rolling; hands stay fisted; asymmetric movements |
| 6 Months | Sits with support; reaches for objects with both hands | Cannot sit even with support; prefers one hand exclusively |
| 9 Months | Sits without support; beginning to crawl | Cannot sit unsupported; drags one side while crawling |
| 12 Months | Pulls to stand; may take first steps | Cannot pull to stand; persistent toe walking; very stiff or very floppy |
| 18 Months | Walks independently; runs; climbs stairs with help | Not walking; abnormal gait pattern; significant balance problems |
⚠️ Important Note: Every child develops at their own pace. Missing one milestone doesn’t necessarily indicate cerebral palsy. However, multiple delays or concerns should be discussed with your pediatrician promptly.
Associated Signs and Symptoms
Beyond movement and posture difficulties, babies with cerebral palsy may exhibit additional signs:
Sensory and Communication Challenges
- Vision problems: Crossed eyes (strabismus), difficulty tracking objects, or cortical visual impairment
- Hearing difficulties: Partial or complete hearing loss affecting speech development
- Speech delays: Difficulty forming sounds due to oral motor challenges
- Drooling: Excessive drooling due to poor muscle control around the mouth
Feeding and Digestive Issues
- Sucking and swallowing problems: Difficulty coordinating feeding, leading to poor weight gain
- Gastroesophageal reflux: Frequent spitting up or vomiting
- Constipation: Due to low muscle tone in the digestive tract
- Oral sensitivity: Extreme reactions to different food textures
Sleep and Behavioral Patterns
- Sleep disturbances: Difficulty falling asleep or staying asleep
- Persistent crying: Excessive fussiness that’s difficult to soothe
- Decreased responsiveness: Seeming less engaged with caregivers or environment
When to Contact Your Doctor
Timely medical evaluation is crucial for diagnosis and early intervention. Contact your pediatrician if you notice:
Immediate Concerns (Contact Doctor Right Away):
- Baby feels very stiff or very floppy when held

Causes of Cerebral Palsy in Newborns
Understanding what causes cerebral palsy can help parents recognize risk factors and, in some cases, identify whether medical negligence may have contributed to their child’s condition.
Common Causes
- Brain damage before birth: Infections during pregnancy, maternal health conditions, genetic abnormalities
- Brain damage during birth: Oxygen deprivation (asphyxia), traumatic delivery, placental problems
- Brain damage after birth: Severe infections (meningitis, encephalitis), head trauma, severe jaundice
- Premature birth: Babies born before 37 weeks have higher risk due to brain immaturity
- Low birth weight: Babies weighing less than 5.5 pounds are at increased risk
Risk Factors
According to medical research, certain factors increase the likelihood of cerebral palsy:
- Multiple births (twins, triplets)
- Complicated or prolonged labor
- Breech presentation at delivery
- Blood clotting disorders in mother or baby
- Maternal infections during pregnancy (rubella, cytomegalovirus, toxoplasmosis)
- Maternal thyroid problems or seizure disorders
Medical Negligence and Birth Injuries in New York
While not all cases of cerebral palsy are preventable, research indicates that a significant percentage of cases result from medical errors during pregnancy, labor, or delivery. According to birth injury legal statistics, cerebral palsy is involved in approximately 41% of birth injury malpractice claims, making it one of the most common birth injuries in medical negligence cases.
Common Medical Errors That May Cause Cerebral Palsy
- Delayed cesarean section: Failing to perform emergency C-section when fetal distress is detected
- Failure to monitor fetal heart rate: Missing signs of oxygen deprivation during labor
- Improper use of delivery instruments: Excessive force with forceps or vacuum extractors causing head trauma
- Medication errors: Incorrect dosage of labor-inducing drugs like Pitocin
- Failure to detect and treat maternal infections: Infections that spread to baby causing brain inflammation
- Failure to diagnose and treat jaundice: Severe jaundice (kernicterus) causing brain damage
- Poor communication among medical staff: Research shows communication breakdowns contribute to more than 1 in 4 birth injury cases

Key Takeaways
- Trust your instincts: If you’re concerned about your baby’s development, discuss it with your pediatrician. Early detection leads to earlier intervention and better outcomes.
- Watch for multiple signs: Cerebral palsy typically involves several warning signs, not just one isolated concern. Pay attention to patterns across movement, muscle tone, and developmental milestones.
- Understand normal variation: Every child develops at their own pace. Missing one milestone by a few weeks doesn’t necessarily indicate a problem, but consistent delays warrant evaluation.
- Developmental timeline matters: According to the NICHD, key milestones include head control by 2 months, rolling by 4 months, sitting by 6 months, and walking by 12-18 months.
- Early intervention improves outcomes: Research shows that therapy started in the first years of life provides maximum benefit due to brain plasticity.
- Not all CP is preventable: However, approximately 41% of birth injury malpractice claims involve cerebral palsy, indicating that medical negligence sometimes plays a role.
- Know your legal rights: If medical errors contributed to your child’s condition, New York law provides a 10-year window to pursue a birth injury claim.
- Free resources are available: Qualified New York attorneys offer free consultations, work on contingency (no upfront costs), and can help families understand their options.
Frequently Asked Questions
What are the first signs of cerebral palsy in a newborn?
The earliest signs in newborns (birth to 3 months) include abnormal muscle tone (feeling unusually stiff or floppy), feeding difficulties, excessive crying or irritability, significant head lag when pulled to sitting, and poor or exaggerated reflexes. However, according to the NICHD, many signs become more apparent as babies grow and developmental milestones are expected. If you notice any concerning signs, discuss them with your pediatrician for proper evaluation.
At what age do cerebral palsy symptoms appear?
Cerebral palsy signs usually appear in the first few months of life, but many children are not diagnosed until age 2 or later. The NICHD reports that symptoms become more noticeable as children reach developmental milestones. Key periods for observation include 2 months (head control), 4 months (rolling), 6 months (sitting), and 12-18 months (walking). Some children with milder cases may not receive a diagnosis until they begin school.
Can you tell if a baby has cerebral palsy at birth?
In most cases, cerebral palsy cannot be definitively diagnosed at birth. While some severe cases may show obvious signs immediately, most diagnoses occur later when developmental delays become apparent. Babies born with known risk factors (extreme prematurity, low birth weight, birth complications) will be monitored closely, but symptoms typically emerge gradually over the first months and years of life as the child’s nervous system matures.
What are the red flags for cerebral palsy in infants?
Major red flags include: baby feels very stiff or very floppy; not reaching developmental milestones (not rolling by 6 months, not sitting by 9 months, not walking by 18 months); showing hand preference before 12 months; persistent asymmetry in movement; feeding difficulties causing poor growth; and excessive crying that’s difficult to soothe. Clinical guidelines from NCBI emphasize that hand preference before age 1 should trigger further assessment, as this typically doesn’t occur until age 2-3 in typical development.
How is cerebral palsy diagnosed in babies?
Diagnosis involves multiple steps: developmental monitoring at regular pediatric checkups; physical examination assessing muscle tone, reflexes, posture, and movement; observation of how the baby moves, plays, and interacts; and brain imaging (MRI, CT scan, or ultrasound) to identify brain abnormalities. Your pediatrician may refer you to specialists such as a pediatric neurologist or developmental pediatrician. The diagnosis process can take several months as doctors monitor whether delays resolve or persist over time.
What causes cerebral palsy in newborns?
Cerebral palsy results from abnormal brain development or damage to the developing brain. Common causes include brain injury before birth (maternal infections, genetic abnormalities), during birth (oxygen deprivation, traumatic delivery, placental problems), or shortly after birth (severe infections, head trauma, severe jaundice). Premature birth and low birth weight significantly increase risk. Research indicates that medical errors during labor and delivery—such as delayed cesarean section or failure to monitor fetal distress—contribute to many preventable cases.
Can cerebral palsy be prevented?
Not all cerebral palsy can be prevented, as some cases result from genetic factors or unavoidable complications. However, research suggests many cases are preventable through proper prenatal care, appropriate monitoring during labor and delivery, prompt response to fetal distress, correct use of delivery instruments, and proper treatment of newborn jaundice. Birth injury statistics show that 41% of birth injury malpractice claims involve cerebral palsy, indicating that improved medical care could prevent a significant percentage of cases.
What is the difference between developmental delay and cerebral palsy?
Developmental delay means a child is behind in reaching milestones but may eventually catch up with appropriate intervention. Cerebral palsy is a permanent condition caused by brain damage or abnormal development, though it doesn’t worsen over time. A child may initially be diagnosed with developmental delay while doctors monitor progress. If delays persist and specific movement or posture problems emerge, a cerebral palsy diagnosis may be made. Not all developmental delays indicate cerebral palsy, but cerebral palsy always involves developmental delays in motor skills.
When should I be concerned about my baby’s muscle tone?
Contact your pediatrician if your baby consistently feels very stiff (like a board) or very floppy (like a rag doll) when held. Other concerning signs include: legs that stiffen and cross when picked up, baby arching back and seeming to push away during holding, difficulty bringing hands together or to mouth, or persistent asymmetry where one side of the body moves differently than the other. According to NICHD guidelines, abnormal muscle tone is one of the earliest and most reliable indicators of potential cerebral palsy.
What legal options exist if my baby’s cerebral palsy was caused by medical negligence?
If medical errors contributed to your child’s cerebral palsy, you may have grounds for a birth injury claim. In New York, families have 10 years from the date of alleged malpractice to file a claim. Most birth injury attorneys offer free consultations and work on contingency (no upfront costs—they only receive payment if they recover compensation). Legal claims can help cover the lifetime costs of medical care, therapy, assistive equipment, and other expenses. Birth Injury Law NY connects families with qualified New York attorneys who specialize in birth injury cases at no cost or obligation.
