Early Signs of Autism: When to Consider a Developmental Screening in Naperville, IL

aba therapy in naperville

Every child grows and learns in their own way. Some kids begin talking early, while others take more time. Some love exploring new environments, while others prefer familiar routines. Differences in development are common, and noticing those differences can naturally bring up questions for parents.

If you’ve recently found yourself wondering about your child’s communication, behavior, or play skills, you are not alone. Families in Naperville, Aurora, Warrenville, Lisle, and surrounding communities often share the same goal: clarity, support, and a trusted partner who understands their child.

That’s where we come in. At Cultivate Behavioral Health & Education, we offer free, research-backed developmental screenings (the M-CHAT-R and CAST) that you can complete from home. And once you’ve taken a screening, our team will personally follow up to help you understand what the results might mean and what comes next.

What Are Early Signs of Autism?

Autism looks different for every child, and there is no one “profile.” However, there are certain developmental markers that may signal that a child could benefit from a developmental screening.

Here are some common early signs that may appear in toddlers or preschoolers:

Communication & Language

  • Limited use of words or gestures
  • Not responding to their name consistently
  • Echoing words or repeating phrases without clear meaning
  • Not yet pointing to show interest (for example, pointing at an airplane in the sky)

Social Interaction & Play

  • Preferring to play alone more often than with others
  • Limited eye contact
  • Not yet showing or sharing interests (like bringing objects to you)
  • Difficulty engaging in pretend play (such as feeding a doll)

Behavioral Patterns

  • Enjoying routines and becoming upset with unexpected changes
  • Hand-flapping or other repetitive movements
  • Strong interests in specific objects or topics
  • Sensitivity to sounds, textures, or lights

Seeing one or more of these does not mean your child has autism. These signs simply tell us: it may be helpful to take a developmental screening.

Why Early Developmental Screening Matters

Early screening helps identify developmental differences as early as possible, which allows families to:

  • Understand their child’s strengths and needs more clearly
  • Access helpful resources sooner
  • Build supportive strategies at home, daycare, or preschool

Research consistently shows that early understanding and early support can make a meaningful difference in communication, learning, and confidence.

Quick Develpmental Screening Tools Parents Can Use at Home

The two most widely used screening tools for early autism signs are:

M-CHAT-R (Modified Checklist for Autism in Toddlers)

  • Designed for children 16–30 months
  • Quick and simple — typically 2–3 minutes to complete
  • Helps identify behaviors that may benefit from further evaluation

CAST (Childhood Autism Spectrum Test)

  • Designed for children 4 years and older
  • Helps parents reflect on how their child plays, communicates, and interacts with others

Both tools are non-diagnostic, meaning they don’t provide a diagnosis, but they can help determine whether a full developmental evaluation would be helpful.
