Early Signs and Symptoms of Autism in Infants | Identifying autism spectrum disorder (ASD) early in life can significantly enhance a child’s development and improve outcomes. While every child develops at their own pace, being aware of the early signs of autism in infants can help parents and caregivers seek appropriate evaluations and interventions. This blog serves as a comprehensive checklist of early signs of autism in infants, organized into various categories, including social communication, behavior, and sensory processing.
Understanding Autism Spectrum Disorder (ASD)
Autism Spectrum Disorder is a neurodevelopmental disorder characterized by challenges in social communication and restricted or repetitive behaviors. The symptoms can vary widely, which is why it is referred to as a “spectrum.” Early diagnosis and intervention are crucial, as they can lead to better developmental outcomes.
The Importance of Early Detection
Research has shown that early intervention can significantly improve developmental trajectories for children with autism. By recognizing the signs early, parents can work with healthcare providers to create individualized plans that address their child’s unique needs. This checklist aims to empower parents and caregivers with knowledge about the potential signs of autism in infants, leading to timely action and support.
Early Signs and Symptoms of Autism in Infants: a Checklist
1. Social Communication Skills
a. Lack of Eye Contact
- What to Look For: Infants typically begin making eye contact within the first few months of life. If your infant consistently avoids eye contact or seems uninterested in looking at faces, it may be a sign to monitor.
- Typical Development: By 2-3 months, infants usually engage in eye contact with caregivers during interactions.
b. Limited Smiling and Facial Expressions
- What to Look For: Observe whether your infant smiles in response to others or shows a range of facial expressions. A lack of social smiling or limited emotional expression may be concerning.
- Typical Development: By 6-8 weeks, most infants begin to smile socially, responding to caregivers’ smiles and voices.
c. Lack of Response to Name
- What to Look For: If your infant does not respond to their name being called by 6-12 months, it may indicate difficulties in social engagement.
- Typical Development: By 6 months, infants typically respond to their name by turning their head or looking toward the caller.
d. Limited Social Referencing
- What to Look For: Notice if your infant looks to you for cues in unfamiliar situations. Limited social referencing, where they do not seek your gaze to gauge reactions, may be a concern.
- Typical Development: By 9-12 months, infants usually look to caregivers for guidance in new or uncertain situations.
2. Communication Skills
a. Delayed Babbling
- What to Look For: Infants typically begin babbling by around 4-6 months. If your infant is not making sounds or babbling, it may be a sign to observe further.
- Typical Development: By 6-9 months, infants should produce a variety of sounds, including consonant-vowel combinations.
b. Lack of Gestures
- What to Look For: Pay attention to whether your infant uses gestures such as pointing, waving, or reaching. A lack of these gestures may indicate communication challenges.
- Typical Development: By 9-12 months, infants typically use gestures to communicate, such as pointing to objects of interest.
c. Limited Vocalization
- What to Look For: Observe if your infant is not vocalizing or making sounds to get attention or express needs. Limited vocalization can be a sign of communication difficulties.
- Typical Development: By 12 months, infants usually produce a variety of sounds and may start to use simple words.
3. Behavioral Patterns
a. Repetitive Movements
- What to Look For: Watch for repetitive movements such as hand-flapping, rocking, or spinning. While some repetitive behaviors can be typical in infancy, excessive or unusual patterns may warrant further observation.
- Typical Development: Infants may engage in repetitive actions, but they should not dominate their play or interactions.
b. Unusual Play Patterns
- What to Look For: Notice if your infant plays with toys in atypical ways, such as lining them up, spinning them, or focusing on parts of the toy rather than using them functionally.
- Typical Development: By 12 months, infants typically engage in functional play, such as pretending to feed a doll or pushing a toy car.
c. Resistance to Change
- What to Look For: Observe if your infant shows distress or agitation when their routine is altered or when introduced to new experiences. High resistance to change may indicate challenges in adaptability.
- Typical Development: While some infants may show mild preferences for routines, they should be able to adapt to changes over time.
4. Sensory Processing
a. Overreactivity or Underreactivity to Sensory Input
- What to Look For: Pay attention to how your infant responds to sensory stimuli, such as loud noises, bright lights, or textures. Overreactivity (extreme distress) or underreactivity (lack of response) can be concerning.
- Typical Development: Infants typically exhibit a range of responses to sensory input, showing curiosity and exploration.
b. Limited Interest in Social Interaction
- What to Look For: Notice if your infant appears indifferent to social interactions, such as not seeking comfort from caregivers or showing little interest in engaging with others.
- Typical Development: By 6-12 months, infants usually seek social engagement through smiles, coos, and reaching for others.

5. Emotional Regulation
a. Difficulty with Self-Soothing
- What to Look For: Observe whether your infant has trouble calming down when upset or distressed. Difficulty with self-soothing can impact emotional regulation.
- Typical Development: Infants typically develop self-soothing behaviors, such as sucking their thumb or cuddling a comfort object, by around 6 months.
b. Limited Expression of Emotions
- What to Look For: Pay attention to whether your infant displays a range of emotions, such as joy, frustration, or sadness. Limited emotional expression may indicate challenges in emotional development.
- Typical Development: By 6-12 months, infants usually express a variety of emotions, including happiness, anger, and fear.
6. Physical Development
a. Delayed Motor Skills
- What to Look For: Monitor your infant’s gross and fine motor skills. Delays in reaching developmental milestones, such as rolling over, sitting up, or crawling, can be a concern.
- Typical Development: Most infants start to roll over by 4-6 months, sit independently by 6-8 months, and crawl by 9-12 months.
b. Unusual Posturing or Movement
- What to Look For: Notice if your infant exhibits unusual postures or movements, such as stiffening their body, having a floppy appearance, or displaying asymmetrical movements. These may indicate underlying neurological or developmental issues.
- Typical Development: Infants typically exhibit a range of movements, showing good muscle tone and coordination as they grow. By 12 months, they should be able to sit, crawl, and begin to pull themselves up to stand.

7. Social Engagement
a. Limited Interest in Social Games
- What to Look For: Observe your infant’s engagement in social games like peek-a-boo or pat-a-cake. A lack of interest or participation in these interactive games may be a sign of social communication difficulties.
- Typical Development: By 9 months, infants usually enjoy interactive games and will often initiate or respond to them with laughter and smiles.
b. Lack of Joint Attention
- What to Look For: Joint attention refers to the shared focus of two individuals on an object or event. If your infant does not follow your gaze or point to objects of interest, it may indicate challenges in social communication.
- Typical Development: By 9-12 months, infants typically engage in joint attention by pointing to or looking at objects while checking back with their caregivers.
8. Parent and Caregiver Observations
a. Gut Feelings and Concerns
- What to Look For: Trust your instincts as a parent or caregiver. If you have concerns about your infant’s development or behavior, it is essential to address them with a healthcare professional. Your observations are valuable in assessing your child’s growth.
- Typical Development: Every child is unique, but parents often notice patterns or behaviors that seem different from their peers. Early intervention is key, so don’t hesitate to seek advice.
b. Family History of Autism or Developmental Delays
- What to Look For: Consider any family history of autism or other developmental disorders. A family history may increase the likelihood of similar challenges in your infant.
- Typical Development: If there is a known family history, it is particularly important to monitor your infant’s development closely and discuss any concerns with a healthcare provider.
9. Seeking Professional Guidance
a. Early Intervention Services
- What to Look For: If you notice several signs from the checklist, it may be time to seek an evaluation from a pediatrician or a specialist in child development. Early intervention services can provide critical support and resources.
- Typical Development: Early intervention can include speech therapy, occupational therapy, and behavioral therapy, tailored to your child’s specific needs.
b. Developmental Screenings
- What to Look For: Regular developmental screenings are essential for monitoring your infant’s growth. Pediatricians often conduct these screenings during well-child visits. If your pediatrician has concerns, they may recommend further assessments.
- Typical Development: Developmental screenings typically occur at 9, 18, and 24 months, but they can be done earlier if there are concerns.
