Eighteen months is a big, busy age. Your toddler is on the move, starting to talk, and letting you know exactly what they want (and do not want). It is also an age when many parents start to wonder, quietly, whether their child is doing everything they “should” be. This guide walks you through what most 18-month-olds are doing, some gentle signs worth a closer look, and what you can do next — all without the panic.

What most 18-month-olds are doing

Children grow at their own pace, so treat these as general guideposts, not a checklist.

Communication. Many 18-month-olds say several single words, point to show you things, and understand far more than they can say. They may shake their head “no,” follow a simple direction, and try to copy sounds.

Motor. Most are walking on their own, and some are starting to run or climb. They might stoop to pick up a toy, push and pull objects, and scribble with a crayon.

Social and play. Toddlers this age often hand you a toy, point at pictures in a book, and show affection. Pretend play is beginning — feeding a doll or holding a toy phone to their ear.

Self-help. Your child may help with dressing by holding out an arm, drink from a cup, and use a spoon (messily).

Gentle red flags worth checking

None of these mean something is wrong. They are simply worth a closer look:

  • Not using any single words
  • Not pointing or gesturing to communicate
  • Not walking yet
  • Not following simple, familiar directions
  • Losing skills they used to have

Simple activities to try at home

  • Narrate your day. Name what you see: “Cup. You want the cup.”
  • Read together and pause so your child can point or fill in a sound.
  • Offer choices (“banana or cracker?”) to invite words and gestures.
  • Get moving with safe climbing, walking to the mailbox, and dancing.

When to talk to your pediatrician

Bring up any of the red flags above at your next visit, and mention anything that has felt “off” to you. You know your child best. Ask about a hearing check if speech or understanding seems delayed — hearing and language go hand in hand.

When to request a free EI evaluation

You do not need a diagnosis or a doctor’s referral to start. In New York, Early Intervention serves children from birth to age 3, and it is completely free to families. You can refer your child to Star EIP directly, or by calling 311. The NYC Early Intervention Program reviews the referral, and an approved agency like Star EIP schedules a free developmental evaluation, usually right in your home. If your child is eligible, you and the team build a plan together and services begin.

Common 18-month worries

If one specific concern is on your mind, these answer pages go deeper:

Milestones are guideposts, not a diagnosis. Only a professional evaluation can tell you what is really going on — and it is a warm, playful process, not a test.

If any of this resonates, trust your instinct and take the next small step. A developmental evaluation is always free. See if your child qualifies.

Star EIP is a New York State–approved Early Intervention agency serving children birth–age 3 across all five NYC boroughs.

Frequently asked questions

What should an 18-month-old be able to do? +

Around 18 months, many toddlers say a handful of words, point at things they want, walk on their own, and copy simple actions like waving or stirring a spoon. Every child is a little different, so think of these as guideposts rather than a pass-or-fail test. If several skills seem far behind, it is worth checking in.

Is Early Intervention free in New York? +

Yes. Early Intervention is a New York State program for children from birth to age 3, and it is free to families. Insurance or Medicaid may be billed, but families pay nothing out of pocket, and Medicaid is not required. Private insurance does not disqualify your child.

Do I need a doctor's referral to start Early Intervention? +

No. You do not need a doctor's referral or a diagnosis. Any parent can make a referral to an agency like Star EIP or by calling 311. The NYC Early Intervention Program then reviews the referral and arranges a free developmental evaluation.

Should I wait and see if my toddler catches up? +

You do not have to wait. A free evaluation gives you real information and peace of mind, and it never leads to anything you do not agree to. Starting earlier simply gives your child more time to grow if support turns out to help.
