Every child develops at their own pace. Some begin talking early, while others take more time. Some are naturally outgoing, while others are quieter or more independent. Because of these differences, it can be difficult to know when a developmental delay is simply part of a child’s unique personality and when it may be worth exploring further.
If you’ve started wondering whether your child may have autism, learning about the early signs can help you decide whether it’s time to speak with your child’s pediatrician. Recognizing potential signs early does not mean your child has autism, but it can help families access evaluations and support sooner when needed.
What Are the Early Signs of Autism?
Autism spectrum disorder (ASD) affects how a child communicates, interacts with others, and experiences the world around them. Signs often become noticeable during the first few years of life, although every child develops at their own pace. These indicators usually present themselves during childhood, although not all children reach developmental milestones at the same time.
Some children show several signs early in life, while others develop as expected for a period before developmental differences become more noticeable.
Early Signs of Autism by Age
Signs in Babies (6 to 12 Months)
Some early developmental differences may begin to appear during infancy.
Parents may notice:
- Limited eye contact
- Smiling less during social interaction
- Limited response to familiar voices
- Fewer back-and-forth facial expressions
- Limited interest in social games like peekaboo
- Not consistently turning toward sounds or voices
Every baby develops at a different rate; thus, just one indicator alone does not point to autism.
Signs in Toddlers (12 to 24 Months)
As communication and social skills continue to develop, additional signs may become easier to recognize.
Some children may:
- Not consistently respond to their name
- Have delayed speech or language development
- Use few gestures such as pointing or waving
- Show limited interest in sharing experiences with others
- Engage in repetitive movements, such as hand flapping or rocking
- Become very upset by changes in routines
- Show unusual reactions to sounds, lights, textures, or other sensory experiences
These are some of the most common reasons parents begin discussing autism with their pediatrician.
Signs in Preschool-Age Children (2 to 5 Years)
As children grow, social expectations become more complex, making developmental differences easier to notice.
Parents or teachers may observe:
- Difficulty starting or maintaining conversations
- Limited pretend or imaginative play
- Difficulty making friends or joining group activities
- Repeating words or phrases frequently
- Highly focused interests in specific topics or objects
- Difficulty adapting to changes in routine
- Strong emotional reactions when routines change
Some children may have strong language skills but continue to experience challenges with social communication.
Early Signs Can Look Different in Every Child
No two autistic children are exactly alike.
While some children show signs of delayed communication, others have developed their language skills at a normal pace but are facing problems in social situations and flexibility. Some are highly sensitive to sounds or textures, while others seek out certain sensory experiences.
The presence of all signs of autism does not matter for an evaluation.
What Behaviors Do Not Automatically Mean Autism?
Many behaviors commonly associated with autism can also occur in children who are developing typically or who have other developmental differences.
For example:
- Speech delays
- ADHD
- Anxiety
- Hearing differences
- Sensory processing differences
- Developmental language disorders
This is why autism cannot be diagnosed based on one behavior or milestone.
When Should Parents Talk to a Pediatrician?
If you notice several developmental differences or if your child seems to be losing previously learned skills, it is a good idea to discuss your concerns with your child’s pediatrician.
Your pediatrician may recommend:
- Developmental screening
- Autism-specific screening
- Referral to a developmental specialist
- A comprehensive autism evaluation
Parents are often the first to notice developmental differences, and sharing those concerns with a pediatrician can help determine whether further evaluation is appropriate.
What Happens During an Autism Evaluation?
A developmental evaluation looks at much more than one behavior or checklist.
The evaluation may include:
- Parent interviews
- Developmental history
- Observations of communication and play
- Social interaction assessments
- Standardized developmental testing
- Input from caregivers or teachers when appropriate
Providers use all of this information to determine whether a child meets the diagnostic criteria for autism spectrum disorder.
How ABA Therapy Can Help
If a child receives an autism diagnosis, ABA therapy may be recommended to help build communication, social, behavioral, and daily living skills.
Before therapy begins, a Board Certified Behavior Analyst (BCBA) completes an assessment to understand the child’s strengths, challenges, and individual needs. A treatment program is designed based on the assessment results and tailored to meet the specific needs of the child.
The focus is on helping children build practical skills they can use at home, at school, and in everyday life.
