Early Signs of Autism in Toddlers: What North Texas Parents Should Know

Autism spectrum disorder (ASD) affects approximately 1 in 36 children in the United States, according to the CDC's most recent data. Early identification and early intervention are the two most powerful factors in determining long-term outcomes for children with autism. The earlier ABA therapy and other supports begin, the greater the child's potential for progress. But many parents in North Texas aren't sure what to look for, or they hesitate to raise concerns with their pediatrician. This guide covers the most important early signs of autism in toddlers by developmental stage.

Why Early Detection Matters

The brain's neuroplasticity, its ability to change, adapt, and form new connections, is greatest in the first three years of life. ABA therapy and other early interventions that start during this window can produce dramatically better outcomes than the same interventions started later. Waiting for a formal diagnosis is not always necessary to access early intervention services in Texas. If you have concerns, act.

Early Signs at 12 Months

By their first birthday, most children show clear social engagement. Signs that may warrant evaluation include: not responding to their name when called, not pointing, waving, or using gestures, not babbling or making consistent sounds, lack of back-and-forth vocalization or smiling with caregivers, and limited or no eye contact.

Not all children who show these signs have autism, there are many possible explanations, including hearing loss. A hearing test and a developmental evaluation are both appropriate next steps.

Early Signs at 18 Months

By 18 months, most children are using at least a handful of words and showing clear interest in other people. Signs that may indicate autism at this stage include: fewer than 6-10 words, not pointing to show interest in things (like a dog or airplane), not imitating actions or sounds, limited pretend play, lining up objects rather than playing with them functionally, and seeming unusually distressed by sounds, textures, or transitions.

Early Signs at 24 Months

By age 2, most children are using 50+ words and starting to combine two words. Red flags at this stage include: not using two-word combinations independently, loss of language or social skills that were previously present (regression), limited social interaction with peers, repetitive body movements like hand-flapping or rocking, insistence on rigid routines, and unusual reactions to sensory input.

Language regression, when a child loses words or skills they previously had, should always be evaluated promptly.

What To Do If You Notice These Signs

If you notice multiple early signs of autism in your toddler, here are the steps to take in Texas:

1. Talk to your pediatrician. Share your specific observations. Request an ASQ (Ages and Stages Questionnaire) or M-CHAT (Modified Checklist for Autism in Toddlers) screening if not already done at your well-child visit.
2. Request a referral for a formal autism evaluation. In Texas, evaluations are conducted by developmental pediatricians, child psychologists, and some neurologists. Waitlists can be long (often 6-12 months), so request a referral as soon as concerns arise.
3. Contact Texas Early Childhood Intervention (ECI). Children under 3 in Texas can access free early intervention services through ECI while you await a formal diagnosis. ECI provides speech therapy, occupational therapy, and other supports at no cost to families who qualify.
4. Contact Belong ABA. You do not need a final autism diagnosis to start the intake process with us. We can begin working with your family while the evaluation is in progress. Call (469) 294-9924.
