How to Identify Signs of Autism in a Toddler: What Parents Should Watch For

The toddler years are filled with exciting milestones. First words, pointing, playing, laughing, following directions, and learning how to interact with others are all important parts of early childhood development. But what happens when your child seems to be developing differently from other children their age?

For some parents, noticing developmental differences can be the first step toward discovering that their child may have autism, but recognizing possible signs of autism in toddlers does not mean that your child definitely has autism.

Children develop at different rates, and some developmental differences can have many possible explanations. However, noticing concerns and discussing them with your child’s pediatrician can help your family get the appropriate screening and support as early as possible.

The American Academy of Pediatrics recommends that children receive autism-specific screening during their 18-month and 24-month well-child visits. Screening can also be appropriate at other times if a parent or healthcare provider has concerns.

At ABLE, we do not provide autism evaluations or diagnoses. Our role begins after a child has received an appropriate diagnosis and is referred for ABA therapy. We provide ABA therapy for children with autism in Tampa, Lakeland, Brandon, Clearwater, and Plant City, with programs designed to help children build meaningful skills through early intervention.

What Are Some Early Signs of Autism in Toddlers?

Autism can look different from child to child. Some children may show several signs, while others may show only a few. According to the CDC, characteristics associated with autism can involve social communication and interaction, repetitive behaviors or interests, and differences in how a child responds to sensory experiences.

Here are some things parents may want to keep an eye on.

Delays in Speech or Communication

One of the most noticeable concerns for many parents is communication.

You may notice that your toddler:

• Is not using words as expected for their age
• Has very few words or is not gaining new words
• Does not use gestures to communicate
• Does not point to show you something interesting
• Has difficulty communicating wants or needs
• Repeats certain words or phrases frequently
• Does not respond consistently when spoken to

Communication differences can be an important reason to discuss your child’s development with their pediatrician.

Limited Social Interaction

Some toddlers with autism may interact differently with people around them.

Parents may notice that their child:

• Does not consistently respond to their name
• Rarely looks toward others when they are speaking
• Seems less interested in interacting with people
• Does not share interests or objects with others
• Has difficulty engaging in back-and-forth interaction
• Does not imitate actions or expressions
• Prefers to play alone much of the time

The CDC identifies differences in social communication and interaction as one of the primary areas associated with autism.

Differences in How They Play

Pay attention to how your toddler plays with toys and interacts with their environment.

Some children with autism may:

• Repeat the same play pattern over and over
• Line up toys or objects
• Focus strongly on parts of toys, such as wheels
• Have difficulty with pretend play
• Become upset when someone changes how they are playing
• Show intense interest in particular objects or activities

Remember that repetitive play by itself does not mean a child has autism. What matters is the overall pattern of development and behavior.

Difficulty With Changes and Transitions

Some toddlers may become very upset when their routine changes or when they are asked to move from one activity to another.

You might notice strong reactions to:

• Changes in daily routines
• Leaving a favorite activity
• Going somewhere unfamiliar
• Changes to the way objects are arranged
• Unexpected events

A preference for routines can be common in young children, but significant difficulty with changes can be worth discussing with your child’s doctor when it occurs alongside other developmental concerns.

Unusual Sensory Responses

Some children with autism experience the world around them differently.

Your toddler may appear especially sensitive or unusually interested in:

• Loud sounds
• Certain textures
• Bright lights
• Smells
• Tastes
• Clothing
• Touch

Some children may also seek certain sensory experiences, such as spinning, rocking, or repeatedly watching objects move.

The CDC notes that unusual reactions to the way things sound, smell, taste, look, or feel can be associated with autism.

One of the Most Important Sign: Losing Skills

One concern parents should take particularly seriously is regression, meaning a child loses skills they previously had.

For example, a child who was using several words may stop using them, or a child who previously interacted socially may suddenly become less engaged.

If your child loses skills they previously had, contact their doctor and share your concerns. The CDC specifically advises parents to act early when a child loses skills or is not meeting developmental milestones.

What Should Parents Do If They Notice These Signs?

If you notice several of these behaviors or simply feel that something about your child’s development concerns you, don’t wait for your child to “catch up” before bringing it up with their doctor.

Start by making an appointment with your child’s pediatrician and explain exactly what you have noticed.

It can be helpful to bring:

• A list of developmental concerns
• Examples of behaviors you’ve noticed
• Information about your child’s communication
• Notes about skills your child has gained or lost
• Videos of behaviors or interactions, when appropriate
• Questions you want to ask the doctor

Your child’s doctor may perform developmental screening and, if appropriate, recommend additional evaluation by a qualified specialist. A screening is not the same thing as an autism diagnosis. A formal diagnosis involves a more comprehensive evaluation that considers the child’s developmental history and professional observations.

Don’t Be Afraid to Ask for an Autism Evaluation

Sometimes parents worry that they are overreacting by asking about autism.

You know your child better than anyone.

If you have concerns about your child’s communication, social development, behavior, or milestones, it is completely appropriate to bring those concerns to your pediatrician.

Early identification can help families understand their child’s needs and connect with appropriate services sooner. The CDC notes that identifying autism as early as possible can help children receive services and supports they need to reach their full potential.

What Happens After an Autism Diagnosis?

Receiving an autism diagnosis can bring many emotions. You may feel relieved to finally have answers, overwhelmed by what comes next, or simply unsure where to begin.

The diagnosis is not the end of the journey. It can be the beginning of understanding your child’s unique strengths and finding the right support.

Depending on the child’s individual needs, families may explore services such as ABA therapy, speech therapy, occupational therapy, early intervention programs, and other developmental supports.

At ABLE, we focus on ABA therapy for children with autism after they have received a diagnosis and are ready to begin services.

Early Intervention ABA Therapy at ABLE

Early intervention can give young children meaningful opportunities to build communication, social, behavioral, and daily living skills.

At ABLE, our individualized ABA therapy programs can help children work toward goals such as:

• Developing communication
• Learning first words
• Requesting help
• Building social skills
• Following directions
• Learning daily routines
• Potty training
• Improving independence
• Practicing transitions
• Developing school-readiness skills

Every child is different, which is why therapy goals are individualized to the child’s strengths, needs, and developmental level.
