As a parent, noticing something different about your child’s development can feel overwhelming , especially when you’re not sure where to turn. You might be Googling symptoms at midnight, or quietly wondering at a well-child visit whether to bring it up.
This guide is designed to help you move from worry to clarity. We’ll walk you through the early signs of autism by age, show you exactly what to do next in the Missouri healthcare system, and explain how local resources in Springfield, Joplin, and Ozark can support your family every step of the way.
What are the most common early signs of autism in toddlers?
The most common early signs of autism in toddlers include delayed or absent speech, limited or inconsistent eye contact, not responding to their name, reduced interest in other children, and repetitive behaviors such as hand-flapping or lining up objects. Most signs appear before age three, and some are noticeable as early as 6 to 12 months. Early identification leads to earlier support, which can make a real difference in outcomes.
Recognizing Signs by Age
Every child develops at their own pace, but autism signs often follow recognizable patterns at different stages. Here’s what to watch for.
Signs of Autism in Babies (6–12 Months)
At this stage, babies are beginning to engage with the world socially. A baby who may be showing early signs of autism might not:
- Smile back when you smile at them
- Babble or make cooing sounds
- Make consistent eye contact during feeding or play
- React when you call their name
- Reach their arms up to be picked up
- Show interest in faces vs. objects
It’s important to note that one or two of these behaviors on their own is rarely cause for alarm. What you’re looking for is a consistent pattern across several behaviors.
Signs of Autism in Toddlers (18–24 Months)
This is often the window when parents and pediatricians first start raising concerns. A toddler who may be showing signs of autism might not:
- Say single words by 16 months or two-word phrases by 24 months
- Point at objects to share interest (e.g., pointing at a dog and looking back at you)
- Follow your pointing gesture when you direct their attention
- Show facial expressions that match the situation (happy, sad, surprised)
- Show interest in playing alongside or with other children
- Wave goodbye or use other common gestures
- Notice or respond when someone nearby is hurt or upset
- Engage in simple pretend play (feeding a stuffed animal, for example)
Some children also show regression, meaning they hit early milestones and then lose them. If your child had words and stopped using them, or was making eye contact and gradually stopped, share that history with your pediatrician right away.
I’m Concerned About My Child’s Development, What Do I Do First?
Feeling concerned is the first step, and acting on that concern is what matters most. Here’s how to get started even before any appointments are scheduled.
Step 1: Start a Behavior Notebook
Before you call the doctor, spend one to two weeks writing down what you’re observing. This is sometimes called the “Notebook Method,” and it makes your pediatrician visit far more productive.
In your notebook, record:
- What you saw — describe the behavior specifically (e.g., “didn’t look up when I said his name five times”)
- When it happened — time of day, setting, what else was going on
- How often — once or twice, or consistently across the week?
- Videos — short phone clips are incredibly helpful for clinicians
You don’t need to be a medical expert. You just need to be an observer of your own child. Your notes will speak for themselves.
Step 2: Talk to Your Southwest Missouri Pediatrician
Your child’s pediatrician is your first and most important partner. At well-child visits, Missouri pediatricians routinely screen for developmental delays using tools like the M-CHAT-R (Modified Checklist for Autism in Toddlers) at 18 and 24 months.
If you have concerns between visits, call and ask for a developmental check-in . When you go, bring your notebook. Be direct: “I’ve been noticing some things that concern me, and I’d like your thoughts.”
A good pediatrician will either refer you for a formal evaluation or direct you to early intervention services. If you feel your concerns are being dismissed and your instincts are telling you otherwise, it is always okay to seek a second opinion.
The Missouri Diagnosis Journey: How to Get an Evaluation
Understanding how the evaluation process works in Missouri will save you time, reduce frustration, and help you advocate for your child more effectively.
Medical Diagnosis vs. Educational Identification: What’s the Difference?
This is one of the most common points of confusion for Missouri families, and it matters.
A medical diagnosis is made by a licensed clinician. This is typically a developmental pediatrician, child psychologist, or neurologist. It is documented in your child’s medical record and is what insurance companies and ABA providers like My World ABA use to authorize services. You pursue this through your pediatrician or a specialty clinic.
An educational identification (sometimes called “educational eligibility”) is determined by your child’s school district. Springfield Public Schools, for example, can evaluate your child under the Individuals with Disabilities Education Act (IDEA) and classify them as eligible for special education services — but this is not the same as a medical diagnosis, and it does not automatically qualify your child for clinical services like ABA therapy. Both can be valuable, and you can pursue them simultaneously.
Local Missouri Resources to Know
First Steps Missouri — If your child is under age three, First Steps is Missouri’s early intervention program. It’s free, it’s statewide, and it can connect your family with developmental therapy, speech therapy, and other supports while you’re waiting for a formal diagnosis. Ask your pediatrician for a referral, or call the First Steps intake line directly.
Springfield Public Schools — Parents as Teachers — Springfield Public Schools offers the Parents as Teachers program for families with children from birth through kindergarten entry. It provides home visits, developmental screenings, and connections to community resources. This is an excellent complement to your medical evaluation process.
Missouri’s Developmental Disability Resource Board (DDRB) — Greene County has a locally funded DDRB that helps fund services for children and adults with developmental disabilities. It can be a critical resource if insurance coverage has gaps.
Frequently Asked Questions
A qualified clinician can diagnose autism as early as 18 months, and research supports that early diagnoses at this age are stable and reliable. In practice, many Missouri families receive a diagnosis between ages 2 and 4. The wait time for a developmental pediatrician appointment in the Springfield and Joplin areas can range from a few weeks to several months depending on the provider, which is why starting the process early matters so much. Your pediatrician can help you get into the referral queue as soon as possible.
Missouri has strong autism insurance protections. Under Missouri law (RSMo § 376.1224), most commercial insurance plans are required to cover the diagnosis and treatment of autism spectrum disorder, including diagnostic evaluations and ABA therapy. Medicaid (MO HealthNet) also covers autism services for eligible children. However, coverage details vary by plan — copays, deductibles, and pre-authorization requirements differ. Before your evaluation appointment, call your insurance company and ask specifically: “Does my plan cover a diagnostic evaluation for autism spectrum disorder, and do I need a referral or prior authorization?” My World ABA’s intake team is also happy to help you understand your benefits before you begin services with us.
