As a parent, you know your child better than anyone. When something feels off — when the milestones aren’t coming, when communication seems different, when behaviors are hard to explain — that instinct matters. But turning that feeling into a conversation with your pediatrician can feel intimidating.

What do you say? What if they don’t take your concerns seriously? What happens after?

At Mestre Behavior, we’ve spent more than 16 years supporting Miami families through every stage of this journey — including the very beginning, when parents are just starting to find words for what they’re observing at home. This guide walks you through exactly how to approach that conversation with your child’s doctor, so you feel prepared and confident when you walk into that appointment.

Most autism evaluations don’t begin with a specialist. They begin with your child’s pediatrician, who serves as the gatekeeper to the evaluation process. A referral from your pediatrician is often required to access developmental specialists, and in many cases, it’s also necessary to begin the insurance authorization process for services like ABA therapy.

This means the conversation you have with your child’s doctor is not just important — it’s the starting point for everything that follows.

The single most helpful thing you can do before your appointment is document what you’ve been observing. Pediatric visits are short, and it’s easy to forget specific examples once you’re in the room.

Keep a simple notes document or use your phone’s notes app to record:

If you have videos, bring them. A short clip of a behavior you’ve observed at home can communicate more clearly than any description. Most pediatricians genuinely appreciate when parents come in with documentation — it makes the visit more productive for everyone.

Many parents hesitate because they don’t want to be wrong, or they worry about overreacting. But expressing a concern is not the same as making a diagnosis — it’s doing your job as a parent.

Here are a few ways to open the conversation clearly:

The M-CHAT-R (Modified Checklist for Autism in Toddlers) is a standardized screening tool recommended for all children at their 18-month and 24-month well visits. If your child has already passed those ages without being screened, or if you’re not sure whether a screening was done, you can simply ask:

“Has [child’s name] been screened for autism? Can we do that today?”

Pediatricians are also required to perform general developmental screenings at 9, 18, and 30 months under standard-of-care guidelines. If your child’s appointments haven’t included a developmental screening, requesting one is entirely appropriate — and the doctor should welcome it.

This happens more often than it should. “Let’s wait and see” or “boys develop later” or “all kids do that” are responses that many parents in our Miami community have heard — and then later regretted not pushing back on.

If you leave an appointment feeling like your concerns weren’t taken seriously, here’s what you can do:

Early intervention is one of the most significant factors in outcomes for children with autism. Waiting months or years for a re-evaluation is time your child can’t get back. Advocating firmly — and kindly — is always worth it.

Once your pediatrician provides a referral, you’ll likely be directed to one of several types of specialists:

The evaluation process can take time. Waitlists for developmental pediatricians in Miami-Dade can run several months. In the meantime, you don’t have to wait to begin support.

This is one of the most important things we tell families at Mestre Behavior: a formal diagnosis is not always required to begin ABA therapy.

For children who are showing developmental differences — in communication, social interaction, play, or behavior — early ABA intervention can begin before a full diagnostic workup is complete. Many insurance plans, including Florida Medicaid, allow ABA services to begin with a qualifying diagnosis from a licensed professional, and our team can help you navigate what documentation is needed.

If you’re in the process of pursuing an evaluation, or you’ve recently received a diagnosis and aren’t sure what the next step looks like, we invite you to reach out. Our team will walk you through the process, verify your insurance benefits, and help you understand what services your child may be eligible for — without any pressure or obligation.

Mestre Behavior serves families across Miami-Dade, including Kendall, Doral, Coral Gables, Westchester, Palmetto Bay, South Miami, and surrounding areas. Our team provides services in both English and Spanish, and we understand the unique experience of navigating healthcare systems in a bilingual household.

If you’ve been putting off the conversation with your child’s doctor, let this be your encouragement to schedule that appointment. The earlier a child receives support, the more powerful the impact — and your instincts as a parent are worth following.
