Parent on the phone at a sunlit kitchen table with a blank notepad, young child playing with blocks nearby

You’ve seen something. Maybe your child stopped waving. Maybe their name gets no response. Maybe play looks different from what other toddlers do. Whatever it was, you’re now reading about early signs of autism late at night. And the real question underneath it is simple: what do I do tomorrow morning?

Here’s the short answer. Book the pediatrician, ask for a developmental screening by name, and ask for a referral for a full evaluation. You do not have to be certain first. Getting on a list early is the most useful thing you can do this week, because you cannot speed up the wait later.

Key Takeaways

You do not need to be sure before you act. Raising a concern is enough to start the process.
Screening and a full evaluation are different things. Ask for both by name.
Evaluation waitlists in South Florida run long, so get on one the same week you notice something.
Write down what you see, with dates. Your notes carry real weight in an evaluation.
Support does not have to wait for a diagnosis. You can do useful work while you wait.

First, Know What You Are Looking At

Your pediatrician is already watching for this, whether anyone said it out loud or not. The American Academy of Pediatrics recommends screening all children for autism at the 18- and 24-month well-child visits, in addition to the ongoing observation that starts at the very first visit.

So noticing something early is not you overreacting. It’s roughly when the process is designed to catch it. The AAP frames this as ongoing surveillance alongside scheduled screening, which is why a concern you raise between visits still counts.

The signs parents bring in are usually small, everyday things:

Not responding to their name by around 12 months
Little or no pointing to share something interesting
Eye contact that is limited, or comes and goes
Losing words or social skills they clearly had before
Lining up toys, or playing with one part of a toy instead of the whole thing
Big reactions to sound, texture, or light
Repeating the same phrase or movement again and again

One item on that list is not a conclusion. A pattern is worth a conversation. And losing skills a child already had is the one to raise quickly, not watch.

Screening and a Full Evaluation Are Not the Same Thing

This confuses almost everyone, and the confusion sets families back months.

Screening is a short questionnaire at a regular visit. It takes minutes. As the AAP puts it plainly, “screening for autism is not the same as diagnosing autism.” A screen sorts children into “no concern right now” and “worth a closer look.”

A full evaluation is that closer look. It can involve a team of professionals like psychologists, speech therapists, occupational therapists, and physicians. It takes hours, sometimes across several visits.

Here’s the part worth writing down. There is no blood test for autism. A diagnosis rests on watching behavior and development, and on what you report. Your notes are real evidence, not just impressions. Start writing them down now, with dates.

How to Talk to Your Pediatrician So You Are Taken Seriously

This is where most families lose time. Not because anyone is careless, but because a worried parent describing a vague feeling is easy to reassure, and a parent with dates and specifics is not.

Go in with three things ready:

A written list of what you have seen, with roughly when each thing started. Two weeks of short notes beats a long speech.
Anything your child could do before and cannot do now. Say this early in the appointment. Losing a skill carries more weight than never gaining one.
Two specific asks. Say them out loud: “I would like a developmental screening documented today,” and “I would like a referral for a full evaluation.”

Naming the screening matters. It puts the result in the chart, giving you something to point to later. Asking for the referral matters just as much, because a screen alone does not book anything.

If you’re told to wait and see, that can be a fair plan. It is only a fair plan with a date on it. Ask for the follow-up appointment before you leave the room. An open-ended “let’s revisit sometime” is how six months disappear.

Get on the Waitlist This Week

Diagnostic waitlists in South Florida are long. Months, commonly. That single fact should reshape your order of operations.

Most families do this backward. They wait until they feel certain, then start calling. The better move is the opposite: get on a list while you are still unsure, and cancel later if your concerns settle. A place you don’t need is easy to give up. A place you never asked for sets you back months.

A few practical things when you call:

Ask what the current wait actually is, in weeks, not “a while.”
Ask what they need from you to hold the spot, and send it the same day.
Ask to be put on a cancellation list, and say you can come on short notice.
Call more than one place. Waits vary a lot between practices.
Write down who you spoke to and when. You will be repeating this story.

Then keep going while you wait. The appointment is not the finish line, and nothing useful has to pause until it arrives.

What Actually Happens at the Evaluation

Parents dread this part. It is usually far gentler than they expect.

Most of it looks like play. Someone sits on the floor with your child. They offer toys. They watch how your child plays, points, looks, and responds. No needle and no scan. Your child isn’t being tested the way adults think of testing.

You will be asked a lot of questions. When did they first walk? Do they answer to their name? How do they let you know they want something? This is where your notes pay off.

A few things that help on the day:

Bring a comfort item. A favorite toy or blanket is fine.
Pick a time of day when your child is usually at their best.
Do not coach your child beforehand. The team needs to see a normal day.
Bring your folder of notes and anything another provider wrote.
Ask when the written report will arrive, and ask for a copy.

You usually will not get a full answer that same day. A written report follows, often in a few weeks. Ask who will walk you through it, and book that conversation before you leave.

What You Can Do While You Wait

Waiting feels like doing nothing. It doesn’t have to be.

The AAP notes that families can begin supportive steps, including play and therapy referrals, even before a diagnostic evaluation. In practice, that means these months are usable.

Keep a short weekly note. One or two lines. What you saw, what set it off, what helped. This becomes the clearest record anyone has.
Film a few ordinary moments. A minute of play, a minute of mealtime. Clinicians find real footage more useful than a description.
Follow the play. Get on the floor, copy what your child is doing, and wait. Joining their activity builds more back-and-forth than redirecting them to yours.
Build in predictability. Same order to the same morning order, with clear warnings before transitions. It lowers daily friction while you sort out the bigger picture.
Talk to a provider before you have paperwork. Most will talk with you without a diagnosis in hand and tell you honestly whether it’s too early.

None of this requires knowing the answer yet. It’s useful either way.

Where ABA Therapy Fits

Applied behavior analysis, usually shortened to ABA, is delivered under a Board Certified Behavior Analyst, a clinician credentialed to assess behavior and design a program. ABA teaches skills in small, measurable steps. It also studies what happens right before and right after a behavior, so the surrounding conditions can change. It’s the therapy families are most often pointed toward after a diagnosis.

A few honest points about timing:

Most insurance plans want a diagnosis before they approve ABA. So the evaluation matters for access, not just for answers.
A good provider will talk with you before any approval exists. Ask your questions early rather than waiting to be “ready.”
Ask what a first month actually looks like, and who you would be working with day to day.

Our Early Achievements ABA Day Program works with children from about 18 months in a preschool-like setting in Coral Springs. Parent training is built in rather than added on, because you’re with your child for the other 20 hours of the day. If you want to understand how coverage usually works before you call anyone, our page on insurance and ABA therapy walks through what plans typically ask for.

Your Next Seven Days

If you do nothing else, do these, roughly in this order:

Today: write down what you’ve noticed and when it started. Dates matter more than detail.
Today: book the pediatrician. When you book, say the visit is about a developmental concern so they set aside enough time.
At the visit: ask for a documented developmental screening, and ask for a referral for a full evaluation.
Same week: call to get on an evaluation waitlist, even if you feel unsure. Ask about cancellation lists.
Same week: start a one-page folder. Put every report, letter, and note in it.
Ongoing: keep the weekly note going, and film a couple of ordinary moments.
Ongoing: have a no-pressure conversation with a therapy provider about what would come next.

None of this needs certainty about what’s happening. It just needs you to start the clocks, because most of them run on someone else’s calendar.

What Not to Do

Two things slow families down more than anything else.

Don’t wait and see without a date attached. “Let’s revisit in six months” is a fair plan when it comes with a scheduled follow-up. It is not a plan with an open ending. If you hear it, ask for the appointment before you leave the room.

Don’t delay an evaluation because you’re not ready for the answer. An evaluation is information, not a verdict. It does not change who your child is. What it changes is what help you can reach, and how fast you can reach it.

FAQs

What If My Pediatrician Says to Wait and See?

Ask for two things before you leave: a developmental screening documented in the chart today, and a follow-up appointment already on the calendar. Both are reasonable requests, and neither is confrontational. If your concerns continue after that visit, a second opinion is common, and nobody will think it strange.

How Long Does the Whole Process Take?

It varies a lot by practice. Start with what you can control: the appointment, the written notes, and getting on a waitlist. Those can all happen in one week. After that, the waiting is mostly out of your hands, which is why starting early matters so much.

Do I Need a Referral Before Anyone Will See Us?

It depends on your plan and the practice. Some evaluators take direct calls from families; others want a referral from the pediatrician first. Ask when you call, because assuming you need one can cost you weeks you didn’t have to give up.

Will an Evaluation Put a Label on My Child?

An evaluation produces a report, and you decide who sees it. Mostly, it opens doors, because most support is gated behind having one. Families far more often regret waiting than they regret finding out.

My Child Is Older. Is It Too Late for This to Matter?

No. Younger is easier in some ways, but skills are teachable at every age, and an accurate picture of how your child learns is useful whenever you get it. The steps above do not change much with age.

Can Therapy Start Before the Diagnosis Comes Through?

Sometimes. It depends on what your plan wants for approval, and that differs plan to plan. Ask a provider directly what they need in hand before anything can begin. The answer is often less than families assume.
