Down Syndrome

A genetic difference with a well-worn path of support — and a community that will welcome you immediately.

If you're here because you're scared, that's okay. You're not alone, and noticing is the first act of advocacy.

Read as much or as little of this page as you have room for today. It will still be here tomorrow.

What this is

Understanding Down Syndrome

Down syndrome is caused by an extra copy of chromosome 21. It brings developmental and intellectual differences that vary widely from person to person, along with some common medical considerations to watch: heart, hearing, vision, thyroid, and atlantoaxial instability.

This is a diagnosis with a deep, organized, generous parent community. You do not have to figure this out alone, and you shouldn't try.

Inclusion works. Children with Down syndrome learn more, and more socially, in general education classrooms with real supports than in segregated settings. That's the default you should start from in IEP meetings.

Could this be it?

Early signs, by age

None of these are a diagnosis, and no child shows all of them. This is a list to help you notice patterns and describe them clearly to someone who can evaluate.

Infant & toddler

  • Usually identified at or before birth through screening or physical characteristics
  • Low muscle tone (hypotonia); slower motor milestones
  • Feeding difficulties in infancy
  • Later first words; strong receptive language relative to speech

Preschool & early elementary

  • Speech that is harder for strangers to understand than for family
  • Strong visual learning; benefits from pictures and modeling
  • Fine motor challenges affecting writing and self-care

Older kids & teens

  • Growing gap in abstract academic content; strengths in social connection and routine
  • Need for explicit instruction in life skills, safety, and self-advocacy
  • Transition planning needs starting by age 14–16

What to do next

In this order, when you're ready

  1. 1

    Enroll in early intervention immediately

    Birth-to-3 Part C services — PT, OT, and speech — are the standard of care and are free. Call your state program now.

  2. 2

    Keep the medical checklist current

    Ask your pediatrician about the Down syndrome health guidelines: cardiac, hearing, vision, thyroid, and sleep apnea screening on schedule. Hearing especially affects speech and school.

  3. 3

    Connect with your local parent group in the first month

    NDSS and NDSC both maintain affiliate directories. Local groups will tell you which providers and schools in your area actually deliver.

  4. 4

    Plan for inclusion from the start

    Ask what supports would make general education work rather than accepting a placement decision first and supports second. Placement is supposed to follow needs.

  5. 5

    Write down what you're seeing

    Dates, examples, the exact words your child used, how long homework took. You don't need a diagnosis to keep a record — you just need a notebook. This becomes the backbone of every conversation that follows.

  6. 6

    If your child is under 3, call early intervention today

    IDEA Part C gives every state a free early intervention program for babies and toddlers from birth to age 3. You do not need a doctor's referral and you do not need a diagnosis — a parent can refer their own child. Search "[your state] early intervention Part C" or ask your pediatrician for the number. For ages 3 and up, the same law (IDEA Part B) makes your local public school district responsible, even if your child doesn't attend school there yet.

  7. 7

    Put your request for an evaluation in writing

    Email or hand-deliver a dated letter to the school principal and the special education director asking for a full initial evaluation, and say what you're worried about. Writing it down starts the legal clock. Ask for a copy of your Procedural Safeguards at the same time.

  8. 8

    Talk with your pediatrician

    A medical visit can rule things in or out — hearing, vision, sleep, iron levels, anxiety — and can open the door to outside evaluations and therapies that run alongside anything school provides.

  9. 9

    Say it out loud to your child, gently

    Kids usually already know something is harder for them. Naming it kindly — "your brain works in a particular way and we're figuring out what helps" — turns shame into a plan.

Try this at home

Small things you can do this week

These are everyday activities, not therapy or instruction. Ten warm minutes beats an hour that ends in tears — stop before either of you is done being pleasant.

Ages 1–65 min

Sign and say together

Pair a simple sign with the spoken word for ten everyday things — more, done, help, eat. Signing supports speech rather than replacing it, and it lowers the frustration while words are catching up.

Ages 4–105 min

Sight words on the fridge

Many kids with Down syndrome are strong visual learners. Big printed words for family names and favorite foods, matched to photos, are often the fastest way into reading.

Ages 5+10 min

One chore, start to finish

Same job, same order, every day — feeding the dog, setting one place at the table. Independence is built by repetition of one whole task, not by helping with many.

These ideas are general parenting suggestions for families reading about Down Syndrome. They aren't therapy, instruction, or medical advice — follow the plan your child's team has set.

A resource worth knowing about

Special Olympics — more than the games you've seen on TV

Most parents picture the competitions. Two of their year-round programs matter far earlier than that, and both are free to families.

Firm Footing is not affiliated with, endorsed by, or partnered with Special Olympics. We recommend them the same way we'd recommend them to a friend — because their programs are real, free, and easy to miss. Availability varies by state and local program.

Looking ahead

When your child reaches their teens

Starting somewhere between 14 and 16, the IEP has to begin planning for life after school: postsecondary goals, independent living skills, vocational training, and connecting with adult services before school ends. Decision-making changes at 18, too.

Your IEP meeting

Before, during, and after

An IEP meeting is a working meeting, not a verdict. You are a full member of the team, and you can ask for another meeting any time.

Evaluations to ask for

Name these specifically in your written request — a general request gets a general answer.

  • Speech-language evaluation including intelligibility and AAC needs
  • Occupational and physical therapy evaluations
  • Cognitive and adaptive behavior assessment
  • Hearing and vision assessment (repeat regularly)
  • Assistive technology evaluation
  • Transition assessment beginning by age 16 (earlier in many states)

Before the meeting

  • Ask for a copy of the draft IEP, the evaluation report, and any progress data at least a few days ahead. You are allowed to read before you decide.
  • Send a short list of your concerns and questions in writing before the meeting so they must be addressed on the record.
  • Write your own one-page "parent input statement" — who your child is, what's working, what isn't, what you want by the end of the year. Ask that it be attached to the IEP.
  • Bring someone: a partner, a friend, a note-taker, or an advocate. You are allowed to bring anyone with knowledge or special expertise about your child.
  • Check your state's rules on recording, and give written notice if you plan to record.

During the meeting

  • Ask each person to say what data they used. "What is that based on?" is a complete, polite question.
  • Slow the meeting down when a term goes by that you don't know. "Can you say that in plain language?" is your right, not an interruption.
  • Test every goal out loud: What exact skill? How will it be measured? What's the target number? Under what conditions? By when?
  • Check that the services page matches the needs page — every need described in the PLAAFP should have a goal, a service, or an accommodation attached to it.
  • If you disagree, don't refuse to sign in silence. Ask for your disagreement to be written into the meeting notes, and ask what the school proposes instead.

Services to ask about

  • Speech-language therapy, with intelligibility and functional communication goals
  • Occupational therapy and physical therapy with stated minutes
  • Specially designed instruction in reading and math with visual, explicit methods
  • Inclusion supports in general education: co-teaching, modified materials, peer supports
  • Life skills and self-advocacy instruction
  • Transition services and community-based instruction as your child gets older

Accommodations to ask about

  • Visual supports and modeling for all new tasks
  • Extra processing and response time
  • Modified assignments that keep the same content and lower the volume
  • Assistive technology for writing and communication
  • Consistent routines with visual schedules
  • Health and safety plan on file with the nurse

After the meeting

  • Send a same-day follow-up email summarizing what was agreed and what's still open. A friendly written summary becomes the record.
  • Read the final IEP against your notes when it arrives. If something is missing or different, say so in writing within days, not months.
  • Calendar the progress reporting dates and ask for the actual data, not just "making progress."
  • If services aren't being delivered, ask for the service log in writing. Missed minutes can mean compensatory services.
  • If you disagree with the school's evaluation, you can request an Independent Educational Evaluation (IEE) at public expense — ask in writing.

Still not sure

Bring the document, or bring the question

If you already have an IEP or evaluation in hand, Decode My IEP will read it with you and flag the vague goals. If you just want to ask something out loud, Sprout answers in plain language.
