You don’t need a diagnosis to start

My six-year-old was ten months old and still wasn’t sitting up on his own.

Our pediatrician had been seeing babies for decades. At that appointment he looked at me and calmly asked whether I’d heard of BabyNet.

I said no.

He explained what it was — South Carolina’s early intervention program, birth to three — gave me the number, and said he strongly suggested I call them now, because starting early intervention early is best.

He didn’t say the word autism. He didn’t need to. And he didn’t need a diagnosis to send me there.

You can start early intervention without a diagnosis. That’s the part I didn’t understand at the time, and it’s the reason I’m writing this.

The thing it took me years to understand

Starting early intervention does not technically make a formal autism diagnosis arrive any faster.

What it does is build a bridge. You end up with a file. You end up with therapists who have watched your child weekly for a year and written down what they saw. You end up knowing the vocabulary, knowing who to call, and having somewhere to be while you wait.

The diagnostic appointment is still a long way off. But by the time you get there, you are not starting from nothing.

I’ve told a lot of parents this since. Most of them have it the other way round in their heads — diagnosis first, then help.

I didn’t have it backwards so much as not have it at all. I did what I was told, in the order I was told it, and I only understood the shape of any of it years later.

What the rules actually say

Early intervention in the United States runs under a federal law called IDEA, and the birth-to-three part of it is Part C. Every state has a program. Mine is BabyNet. Yours is called something else — Early On, First Steps, Help Me Grow, dozens of names.

Three things are worth knowing, and almost nobody told me any of them.

A diagnosis is one way in, not the only way. A child can qualify through a developmental delay, through a diagnosed condition, or in some states through being at risk of a delay. Eligibility is decided by the people who evaluate your child, not by a label you arrive holding. States set their own thresholds for how much delay counts, and they vary a lot, so yours may not match mine.

You can refer your own child. You don’t need a doctor to do it for you. Search your state’s name plus “Part C early intervention,” or call 211 and ask. Then say: I have concerns about my child’s development and I’d like to request an evaluation.

There is a clock, and it starts when you call. Federal rules give the program 45 days from the referral to complete the evaluation and hold the meeting where your child’s plan is written. That plan has a name — an IFSP, an Individualized Family Service Plan. (If you’ve heard of an IEP, that’s the school-age version. The IFSP runs birth to three and the IEP takes over from there.) Forty-five days from the referral — not from the day you get around to signing the consent forms. I didn’t know that number existed for years. It would have changed how I spoke to people.

That 45-day rule is birth to three only. If your child is already three or older, you’re dealing with the school district instead, under a different part of the same law. The federal default there is 60 days from the day you sign the consent form, and some states set their own timeframe instead of using it.

The difference matters more than the numbers do. Early intervention’s clock starts when you call. The school district’s clock starts when you sign. With a district, the stretch between asking and signing is time nobody is counting — so don’t let a consent form sit on your counter.

I’m not a lawyer and this isn’t legal advice. I’m telling you the name of the thing so you can look it up and so you have the right words if someone tells you something that doesn’t sound right.

They told us to wait

Here’s the part the tidy articles leave out.

I called BabyNet, like my pediatrician said. And they told us to wait.

So I waited. It was 2021 and the world was in pieces — lockdowns, e-learning, everybody anxious and stuck in their houses. I was pregnant again, exhausted, and I had no idea the process was something you could push on. I took the answer I was given.

In January 2022 I was with family. I watched my son — one and a half by then — playing beside another child, and I saw it. Not a list of symptoms. Just how differently he played, how differently he was.

I went home and I called again, and this time I wasn’t going to take no for an answer. I’d known since the first week he was born that something was going on. I didn’t have a word for it and I didn’t need one.

They accepted him. And they apologized for not taking him to begin with.

I want that written down somewhere a tired parent can find it. Being told to wait is not the same as being told no. You are allowed to call back.

How long it actually took

Both of my younger sons went into early intervention at around ten months old.

My six-year-old was referred at ten months in 2021, told to wait, accepted at about a year and a half in January 2022 — and his diagnostic interview was in January 2024.

Then the paperwork came around March.

That last bit caught me out too, so I’ll say it plainly: the interview is not the day you find out. Somebody has to write the report. Then you wait for the report. After two and a half years of waiting, there was another two months or so of waiting at the end of it.

My four-year-old went straight in at ten months in 2023, because by then I knew exactly what to do. He was diagnosed in July 2025.

Nearly three years. Then a bit over two.

Some of that was COVID — there was an enormous backlog and we were in the middle of it. But the waits are long everywhere. A national survey of autism centers found about 61% had waits of more than four months, and around one in seven were over a year. That survey ran in late 2022 and early 2023, and only about 11% of the centers asked responded — it’s the best national picture available, not a precise one. Yours could be shorter. Mine were much longer.

If you are somewhere in the middle of a wait like that and it feels unreasonable: it is unreasonable. You’re not being impatient.

What those years actually held

Here’s what I want you to take from those numbers, though.

I didn’t spend three years waiting. I spent three years in therapy appointments.

Occupational therapy. Speech. Physical therapy for a while. A BabyNet caseworker — a special instructor — who was our stepping stone into the whole process.

None of that required a diagnosis. All of it started years before one existed.

ABA was the exception, and it’s worth being exact about why. My six-year-old started it after his diagnosis came through, and my four-year-old is on the waitlist for it now. Strictly speaking you don’t need an autism diagnosis to receive ABA — but insurance coverage is built around the diagnosis, and without one most families are paying out of pocket. Which amounts to the same thing for most of us. Ask your own plan directly rather than assuming either way.

When people say “the waiting list year,” it sounds like a year spent sitting still. It isn’t. It’s a year — or three — of someone coming to your house, and your child getting help, and you slowly learning what any of it means.

Somewhere in there one of those early therapists handed me a first/then board. I barely used it, and it turned out to have worked anyway.

What a special instructor actually does

Our first special instructor did explain her job to me. I was too exhausted to take it in, and I didn’t really understand what she did until I’d felt it working.

She was the first person on our team — there while we waited to be picked up by speech and occupational therapy. There’s a waitlist inside the waitlist, and she’s what filled it.

A special instructor works with babies and toddlers who have delays, and the thing that surprised me is that they mostly work on you. Not a lesson plan for your child. Coaching for the parent, inside the things you already do — meals, getting dressed, playing on the floor.

They cover the broad areas: communication, movement, thinking, how a child handles themselves and other people. They sit on the same team as the speech therapist and the OT and the physical therapist, all working from one plan.

For me, early on, they were the way in. I didn’t know anything. Somebody came to my house and started explaining.

The house part isn’t incidental, by the way. Birth-to-three services are meant to happen in what the law calls natural environments — your home, your routines, wherever your child already is. It isn’t a clinic you drive to. It’s someone arriving in your living room while you’re still in yesterday’s clothes.

What changed, and what didn’t

We eventually stopped in-person special instruction. Not because it hadn’t worked — because by then we didn’t need someone coming to the house for it.

I still have a special instructor. She’s remote now, and I can contact her with a question about anything, and I do.

I want to be careful how I say that, because it would be easy to read as don’t bother. It was absolutely the right thing at the start — when I was exhausted, pregnant again, and completely ignorant about all of it.

What you need in month two is not what you need in year two. Letting go of something that has done its job isn’t quitting. It’s the thing having worked.

I don’t think any of it was wasted. Everything helps, whether you can see it helping or not. The parents get educated. The kids get used to other people being around, and being asked to do things, and that’s its own kind of practice.

The second time was easier, and I want to be honest about why

Going through it again with my four-year-old was faster, and I’d love to tell you it was because I’d become some kind of expert.

Partly it was. I knew the process. I knew what to say on the phone, what the words meant, what came next.

But also the world was opening back up. The backlog was easing. Some of what made the first time so slow was just when it happened. I’d rather tell you that than let you think the difference was all me.

If you’re at the beginning of this

Four things, and none of them need a diagnosis.

Find your state’s program. Search your state plus “Part C early intervention,” or call 211. It won’t be called BabyNet unless you’re in South Carolina.

Call them yourself. You don’t need a referral. Say you have concerns about your child’s development and you’d like to request an evaluation.

Write down the date you called. That’s when the 45 days start.

Find your state’s Parent Training and Information Center. There’s one in every state, it’s federally funded, and it’s free. They know your state’s rules far better than I do, and they exist specifically to help parents who are in the middle of this.

The evaluation itself shouldn’t cost you anything. Ongoing services are a separate question and the answer varies by state — ask directly rather than assuming.

What I’d say to you

You do not have to earn help with a diagnosis.

If something in you has been saying for months that something is going on — the thing I’d felt since the first week he was born — that is enough to make a phone call. Nobody is going to ask you to prove it first.

And if they tell you to wait, write down the date, and call back.
