Intro
Many parents begin exploring autism evaluations after noticing developmental, behavioral, or social differences in their child. In some cases, signs may appear during toddler years. In others, concerns become more noticeable later as social and academic expectations increase.
Because autism spectrum disorder (ASD) presents differently from child to child, the early signs are not always obvious. Some children show clear communication or developmental delays, while others may have more subtle social, sensory, or behavioral differences.
This guide reviews common early signs of autism by age and explains when families in New Jersey may consider seeking an evaluation.
Autism Signs in Babies and Toddlers (12–24 Months)
Some autism-related signs may appear during infancy or toddler years.
Possible signs can include:
- Limited eye contact
- Reduced response to name
- Delayed speech or language development
- Limited pointing or gesturing
- Reduced interest in social interaction
- Repetitive movements or behaviors
- Strong reactions to sounds, textures, or sensory input
Not every child showing one or two of these behaviors has autism, but persistent developmental concerns may warrant further evaluation.
Signs of Autism in Preschool-Age Children (3–5 Years)
As children enter preschool years, social and communication differences may become more noticeable.
Parents or teachers may observe:
- Difficulty with peer interactions
- Repetitive play patterns
- Strong preference for routines
- Intense or highly focused interests
- Difficulty with transitions
- Literal interpretation of language
- Emotional regulation difficulties
Some children may also show overlapping signs associated with ADHD, anxiety, or sensory processing challenges.
Signs of Autism in School-Age Children
In school-age children, autism signs may present differently than they do in younger children.
Some children perform well academically while still experiencing:
- Social communication difficulties
- Challenges making or maintaining friendships
- Sensory sensitivities in classroom settings
- Difficulty understanding social cues
- Rigidity around routines
- Emotional exhaustion after school
In some cases, concerns become more noticeable as social expectations increase with age.
Autism Signs in Girls
Autism may present differently in girls than in boys.
Some girls:
- Mask or camouflage social difficulties
- Mimic peer behaviors socially
- Develop strong coping strategies
- Show fewer outward repetitive behaviors
- Receive anxiety or ADHD diagnoses before autism is considered
Because of this, some girls are identified later or initially overlooked during early screening.
What If Symptoms Seem Mild?
Autism exists on a spectrum, and symptoms can vary widely in intensity.
Some children may:
- Speak well academically
- Perform strongly in school
- Appear socially engaged at times
while still experiencing meaningful social, sensory, or emotional challenges.
A comprehensive evaluation can sometimes help clarify whether autism, ADHD, anxiety, learning differences, or other developmental factors may be contributing.
When Should Parents Consider an Evaluation?
Parents may consider an autism evaluation when:
- Developmental concerns persist over time
- Social or communication difficulties affect daily life
- Teachers or pediatricians express concerns
- Emotional or behavioral struggles increase
- There are questions about ADHD versus autism
- A child seems significantly different from peers socially or behaviorally
Early identification may help families access:
- Educational supports
- Therapy services
- School accommodations
- Behavioral interventions
- Greater diagnostic clarity

Final Thoughts
