Early Signs of Autism in Young Children: When to Seek an ABA Evaluation in New Jersey
When your child misses a developmental milestone or shows unexpected behavior, the questions flood in: Is this normal? Should I be worried? Who do I call? If your instinct is telling you something feels different, listen to it. Early identification of autism can change your child’s developmental trajectory.
The first 3-5 years of life are critical for brain development. Children who receive autism diagnosis and intervention early (ideally before age 5) see significantly better long-term outcomes across communication, social skills, and adaptive behavior. At Children’s Specialized ABA, partnered with RWJBarnabas Health, we’ve spent years helping New Jersey families recognize these early signs and take action quickly.
Here’s what every parent should know about autism in young children, what to watch for, and how early ABA evaluation can help.
What Is Autism Spectrum Disorder in Young Children?
Autism Spectrum Disorder (ASD) is a neurodevelopmental difference that affects how children communicate, process social information, and respond to their environment. It’s called a “spectrum” because autism looks different in every child. Some children are non-speaking or minimally verbal. Others have strong language skills but struggle with social interaction. Some show extreme sensory sensitivities; others don’t.
Autism is not a behavior problem or a lack of discipline. It’s a neurological difference present from birth, though signs may not become obvious until age 1-3 when developmental differences become more apparent. The critical point: autism is not something to fix or cure. But early intervention through ABA therapy and other services can help your child develop critical life skills faster and with less struggle.
Red Flags: Early Signs of Autism in Children Ages 12-36 Months
Developmental pediatricians and autism specialists look for specific patterns in babies and toddlers. If your child shows any of these signs, don’t panic, but do reach out for an evaluation. Early assessment is always the safer choice.

Social and Communication Red Flags
By 12 months, most babies point to objects to share interest (“Look, a dog!”), respond to their name, and show joint attention (looking where you’re looking). Autism often involves differences in these core social behaviors:
- Doesn’t respond to their name by 12 months, or only sometimes responds
- Limited or absent eye contact, especially during conversation
- Doesn’t point to objects or people to show interest
- Doesn’t follow your pointed finger or gaze
- Delayed speech or minimal vocalization by 18 months
- Repeats words without understanding or using them meaningfully (echolalia)
- Difficulty with back-and-forth interaction (you smile, they don’t smile back)
- Prefers playing alone rather than alongside other children
- Doesn’t imitate your actions or gestures (clapping, waving)
Behavioral and Sensory Red Flags
Children with autism often show repetitive, restrictive patterns of behavior or extreme sensory responses:
- Repetitive movements: hand flapping, spinning, lining up objects, watching spinning things
- Intense, narrow interests focused on specific objects or topics
- Resistance to change in routines; extreme distress when things change unexpectedly
- Unusual sensory behaviors: sniffing objects, covering ears, spinning, seeking intense movement
- Walking on tiptoes; unusual posture or motor coordination
- Strong or unusual food preferences; only eats certain textures
- Extreme reactions to sensory input: distressed by certain sounds, lights, textures, or smells
- Doesn’t imitate play; lines up toys rather than playing with them functionally
How ABA Evaluation Works in New Jersey
If you’re seeing signs that worry you, the first step is getting a professional evaluation. A comprehensive ABA assessment is different from a pediatrician screening or developmental assessment. It provides detailed, behavior-based information about your child’s current skills and where support would help most.
At Children’s Specialized ABA, our ABA evaluation process focuses on:
- Direct observation of your child in different settings (home, clinic, community)
- Structured assessment tools (ADOS, VB-MAPP, ABLLS) that measure communication, social, play, and adaptive skills
- Parent interview about developmental history and current concerns
- Detailed behavior analysis identifying strengths and areas for growth
- A written report with specific skill recommendations and therapy recommendations
Many New Jersey families qualify for ABA services through NJ FamilyCare coverage, which makes early intervention accessible. Even if you’re not certain about diagnosis, starting evaluation early is always the right call. Many toddlers show some autistic traits; a formal assessment clarifies whether your child needs support and what that support looks like.
Early Intervention and ABA: Why Starting Before Age 5 Matters
Research is clear: children who receive intervention before age 5 show better outcomes. A landmark study from UCLA found that children who received early intensive ABA therapy (20-40 hours per week) had more typical IQ scores, better language skills, and higher rates of placement in mainstream schools by age 6 compared to children who started therapy later.
But you don’t need 40 hours a week. Even 10-15 hours of targeted ABA per week, starting early, makes a measurable difference in your child’s development. The key is starting now, not waiting to see if your child “grows out of it.” In early childhood, your child’s brain is most malleable. Skills learned now become foundation for everything that follows.
In-home ABA therapy is particularly valuable for young children because it teaches skills in the environments where your child actually needs them: home, community, daycare. Your child learns communication with family, social skills with neighbors, and self-care routines in the spaces where those skills matter most. Children’s Specialized ABA coordinates this support directly in your home and community, removing barriers to consistent, effective intervention.
What Happens After an Autism Diagnosis?
If evaluation confirms autism, what comes next? A diagnosis is not a tragedy. It’s clarity. It means you have a name for what you’ve been observing, access to services, and a roadmap for support.
With a diagnosis, most New Jersey families become eligible for:
- In-home ABA therapy to build communication, social, and adaptive skills with support from a Board Certified Behavior Analyst (BCBA)
- Speech-language pathology if communication is affected
- Occupational therapy for sensory, motor, or daily living skills
- Educational support through your school district’s special education services
- Family support services including parent coaching and resource connection
Children’s Specialized ABA has been partnering with RWJBarnabas Health to provide coordinated care across medical and behavioral domains. This means your child’s ABA therapy is integrated with any other healthcare needs, giving you one coordinated support system rather than juggling multiple providers.
FAQ: Common Questions About Early Autism Signs and ABA
My child has some autistic traits but talks and makes eye contact. Could this still be autism?
Yes. Autism presents very differently across children. Some children have strong spoken language but struggle with social understanding. Others have language delay but are socially engaged. All of these can be autism. Only a formal evaluation from a specialist can clarify whether your child meets diagnostic criteria. If you’re concerned, get assessed. It’s always better to know.
My pediatrician said to “wait and see.” Should I listen?
Pediatricians are not autism specialists. If you’re seeing red flags, waiting is a risk you don’t need to take. A specialist evaluation is low-stakes and high-value. Even if your child doesn’t have autism, you get answers. If they do, early intervention becomes possible. Request an ABA assessment and get clarity.
Does autism diagnosis mean my child won’t go to mainstream school?
Not at all. Many autistic children attend mainstream schools, some with support and some without. Others benefit from specialized settings. The diagnosis itself doesn’t determine placement. Early intervention, including ABA, actually improves the likelihood of successful mainstream school inclusion by building foundational skills before kindergarten. The goal of early ABA is to help your child access the education and community life they want, whatever that looks like.
How much does an ABA evaluation cost?
If your child is covered by NJ FamilyCare, Medicaid, or most private insurance plans, evaluation and ongoing ABA therapy is typically covered. Out-of-pocket costs vary. Many families discover they qualify for FamilyCare and don’t pay anything. It’s worth checking your specific coverage. We can help you navigate insurance and understand your benefits.
What if I’m wrong and my child doesn’t have autism?
Then you have a child who received excellent developmental support from a behavior specialist. Many of the skills built in ABA (communication, social engagement, regulation) benefit all children. There’s no downside to early support. The upside is enormous.
Taking the Next Step: What to Do This Week
If anything in this post resonates with your experience with your child, take action this week:
