Growing in their own time

Baby milestones, without the race

A calm place to notice what is unfolding, find the right official checklist, and know what to do when something is tugging at you.

Milestones help start a conversation. They do not diagnose a child, grade a parent, or turn development into a competition.

Growing together

Before you choose an age

Four things that make the guide more useful

Monitoring is not screening

Monitoring is what families and clinicians notice over time. Screening uses a validated questionnaire at specific visits. This page can support both conversations, but it cannot replace a developmental screen.

Premature babies may use corrected age

Through about age two, clinicians often subtract the number of weeks a baby was born early from their chronological age. Ask the pediatrician or NICU follow-up team which age to use for your child.

Development can be uneven

A child may pour energy into movement while language looks quieter, or talk early while motor skills take longer. Look for change across time rather than expecting every area to move at the same speed.

Every language counts

Learning more than one language does not cause a language disorder. Count meaningful words across all the languages your child uses, and tell the clinician what you hear in each one.

Development in motion

Notice the wave, not a prediction

Babies do not build one skill at a time in a smooth line. You may notice a stretch of intense practice, more need for closeness, or several new abilities appearing near one another. That can be a helpful way to watch development—as long as it does not become a calendar that tells you what your baby must do this week.

Connection & attention

What you might notice: Longer eye contact, turning toward familiar voices, studying faces, sharing smiles or checking back to make sure you are near.

How to meet it: Pause when they look or sound toward you. Answer with your face, voice or touch, then give them room to respond again.

Movement & reach

What you might notice: More kicking, rolling attempts, rocking, pulling up, cruising or repeating one movement until the whole room is tired of it.

How to meet it: Offer safe floor time and an uncluttered place to practice. Let effort belong to them instead of placing their body into a skill.

Sounds & meaning

What you might notice: New sounds, gestures, pointing, copying, watching your mouth or understanding more words than they can say.

How to meet it: Name what has their attention, answer their sounds and leave small pauses. Conversation begins before recognizable words do.

Patterns & independence

What you might notice: Dropping, filling, opening, hiding, sorting, testing cause and effect—or insisting on doing a familiar task without help.

How to meet it: Repeat simple games, offer two manageable choices and expect practice to look messy. Curiosity is doing real work.

A wave is an observation, not an explanation

Clinginess, difficult sleep, feeding changes or fussiness are not proof that a developmental change is happening. They can also come from hunger, discomfort, illness, a changed routine or simply a hard day. Use the pattern to get curious, not to explain away symptoms or delay a call.

This approach draws on the American Academy of Pediatrics’ model of ongoing developmental surveillance and Harvard’s research on responsive, back-and-forth interaction. It does not reproduce or endorse a proprietary developmental-leap schedule. Read the AAP guidance and the Harvard Center on the Developing Child overview.

Choose their age

Bring the right checklist to the next visit

Start with the age your child has most recently completed. Each link jumps to a gentle, on-page guide with an official CDC checklist at the end.

CDC checklists describe things most children—about 75% or more—can do by an age. They are communication tools, not developmental standards or a substitute for formal screening.

A closer look

Age by age, without turning childhood into a test

Open the age you need. Inside you’ll find a parent-friendly snapshot, simple ways to support practice, and the official checklist to bring to a well visit. These are patterns to notice, never a score to chase.

2 monthsFaces, voices and the first back-and-forth

The earliest development is relational. Your baby is beginning to organize familiar voices, faces, touch and movement into a world that feels more predictable.

Connection & relationships

Settles at least sometimes when held or spoken to
Looks closely at a familiar face
Offers an early social smile during warm interaction

Communication

Makes small sounds besides crying
Changes expression or movement in response to a voice or loud sound

Thinking & play

Tracks a person moving nearby
Studies a face or simple toy for a few moments

Movement & hands

Moves both arms and legs
Briefly opens the hands
Begins lifting and holding the head during supervised tummy time

Try this together

Copy one sound and wait for another
Offer short, supervised tummy-time moments when awake
Talk through feeding, dressing and bathing in your natural voice

Keep in mind: Two months is still very new. Watch the whole pattern—feeding, alertness, movement, hearing and connection—not one isolated performance.

Open the official 2 months checklist &nearr;

4 monthsReaching, cooing and asking you to stay

Interaction becomes more intentional. A baby may smile, move or vocalize to begin an exchange—and notice when you answer.

Connection & relationships

Smiles to invite attention
Chuckles or shows clear delight during play
Uses gaze, sound or movement to keep an interaction going

Communication

Coos with open vowel-like sounds
Answers your voice with sounds of their own
Turns toward a familiar voice

Thinking & play

Studies their hands
Anticipates feeding when a breast or bottle appears

Movement & hands

Keeps the head steadier when held
Brings hands toward the mouth and bats at toys
Pushes onto forearms during supervised tummy time

Try this together

Place one safe toy within reaching distance on the floor
Follow their gaze and name what they are studying
Pause during songs and conversations so they can take a turn

Keep in mind: Interest comes in short windows. Looking away, yawning or fussing can mean your baby needs a break rather than more stimulation.

Open the official 4 months checklist &nearr;

6 monthsFamiliar people, busy hands and joyful noise

A six-month-old is often more socially expressive and physically active. Exploring with the mouth and hands is part of learning, not misbehavior.

Connection & relationships

Recognizes familiar people
Laughs and enjoys looking in a mirror
Shows clear preferences and signals when they are finished

Communication

Takes turns making sounds
Experiments with squeals, raspberries and changes in pitch

Thinking & play

Reaches deliberately for a wanted object
Explores safe objects with hands and mouth
Closes the mouth or turns away to communicate fullness

Movement & hands

Rolls from tummy toward the back
Pushes up with straighter arms on the tummy
Uses hands for support while learning to sit

Try this together

Offer safe objects with different textures to grasp and inspect
Put a toy slightly to one side to invite reaching and turning
Read a sturdy book and let touching be part of the reading

Keep in mind: Rolling direction and sitting style vary. Floor time gives the body more useful practice than long stretches in positioning equipment.

Open the official 6 months checklist &nearr;

9 monthsFinding you, finding objects and moving with purpose

People and objects now have a stronger place in memory. Separation may feel bigger precisely because your baby understands that you can leave.

Connection & relationships

May be wary or clingy with unfamiliar people
Shows several recognizable facial expressions
Looks toward you when their name is called and reacts when you leave

Communication

Strings repeated sounds together in babble
Raises arms or uses another gesture to ask to be picked up

Thinking & play

Looks for a dropped or partly hidden object
Experiments by banging objects together

Movement & hands

Gets into or maintains a sitting position without support
Passes an object between hands
Uses the fingers in a raking motion to gather small pieces of food

Try this together

Play simple hiding games with a toy partly visible
Repeat their babble, then add one simple real word
Create safe floor space for rolling, scooting or crawling attempts

Keep in mind: Not every baby crawls in the same way, and some skip classic hands-and-knees crawling. Discuss movement quality or asymmetry that concerns you.

Open the official 9 months checklist &nearr;

1 yearGestures, simple games and standing tall

Around the first birthday, communication includes looks, gestures, sounds and actions—not words alone. Shared games are doing developmental work.

Connection & relationships

Joins familiar social games such as pat-a-cake
Shares enjoyment and checks your reaction

Communication

Waves or uses another familiar gesture
Uses a special name for a parent or caregiver
Pauses or changes course briefly when hearing a familiar limit such as “no”

Thinking & play

Places an object into a container
Searches for something they watched you hide

Movement & hands

Pulls up and moves while holding furniture
Picks up small food with thumb and fingertip
Practices drinking from an open cup with adult help

Try this together

Narrate one-step routines: shoes on, cup down, lights off
Offer containers to fill, empty and refill
Respond to points and gestures as meaningful communication

Keep in mind: Independent walking is not required at the first birthday. Look for progress in mobility and bring any concern about tone, strength or symmetry to the clinician.

Open the official 1 year checklist &nearr;

15 monthsShowing, pointing and trying it independently

The toddler is becoming an active partner: showing you interesting things, copying actions and experimenting with how everyday objects work.

Connection & relationships

Shows you an object simply to share interest
Copies another child's action during play
Expresses affection and excitement in recognizable ways

Communication

Attempts one or two words beyond names for caregivers
Looks toward a familiar object when it is named
Points to request help and follows a direction supported by gesture

Thinking & play

Tries familiar objects for their usual purpose
Stacks two small objects

Movement & hands

Takes a few independent steps
Uses fingers to bring food to the mouth

Try this together

When they approximate a word, repeat it and add one more word
Let them help with safe routines such as placing socks in a basket
Offer blocks, cups and spoons for purposeful imitation

Keep in mind: Words may be imperfect and still count when they are used consistently with meaning. Gestures and understanding are part of communication too.

Open the official 15 months checklist &nearr;

18 monthsShared attention, pretend play and confident movement

A young toddler often moves farther from you while still checking that you are close. Pointing to share interest is different from pointing only to obtain something.

Connection & relationships

Moves away to explore, then checks back
Points to share something interesting
Looks through a few pages with you and helps with dressing routines

Communication

Attempts several words beyond names for caregivers
Follows a familiar one-step direction without needing a gesture

Thinking & play

Copies simple household actions
Uses a toy in a recognizable way, such as moving a toy car

Movement & hands

Walks without holding on
Scribbles and begins using a spoon
Climbs onto and down from low furniture with growing control

Try this together

Build pretend play from daily life: feed the doll or tuck in the bear
Offer chunky crayons and paper without asking for a picture
Use short directions during routines and allow time to respond

Keep in mind: Routine developmental screening and autism-specific screening are recommended around this visit. Screening is offered to every child; it is not a diagnosis.

Open the official 18 months checklist &nearr;

2 yearsTwo-word ideas, big feelings and fast-moving bodies

Language, independence and emotion all expand together. A two-year-old may understand far more than they can calmly express.

Connection & relationships

Notices when another person is upset
Looks to your face for information in an unfamiliar situation

Communication

Combines at least two words into a meaningful phrase
Points to named pictures or body parts
Uses a growing range of gestures beyond waving and pointing

Thinking & play

Uses both hands together for a task such as opening a container
Experiments with switches, knobs and buttons
Combines objects in early pretend play

Movement & hands

Runs and kicks a ball
Walks up a few stairs with or without help
Uses a spoon with increasing success

Try this together

Expand a short phrase by one or two words instead of correcting it
Name feelings while holding the boundary
Offer simple puzzles, posting games and safe objects to open and close

Keep in mind: Count meaningful words across every language your child uses. Learning more than one language does not cause a speech or language disorder.

Open the official 2 years checklist &nearr;

30 monthsPretending, problem-solving and joining other children

Play becomes more symbolic and social. A child may move between playing beside peers, briefly joining them and returning to their own plan.

Connection & relationships

Plays near other children and sometimes with them
Invites you to notice an accomplishment
Follows familiar routines with a reminder

Communication

Uses a growing vocabulary—often around fifty words or more
Combines words, including an action word
Names familiar pictures and begins using words such as “I,” “me” or “we”

Thinking & play

Uses one object to stand for another during pretend play
Solves a simple physical problem and follows a two-step direction
Shows recognition of at least one color

Movement & hands

Twists lids or handles
Removes some loose clothing
Jumps with both feet and turns book pages one at a time

Try this together

Let a box become a bed, bus or kitchen and follow their idea
Give related two-step directions during real routines
Make room for jumping, carrying, pouring and supervised helping

Keep in mind: A standardized general developmental screen is recommended around 30 months. A milestone page cannot replace that validated screening process.

Open the official 30 months checklist &nearr;

3 yearsConversation, friendship and doing more for themselves

The preschool years bring longer exchanges and more interest in peers. Imagination grows faster than judgment, so connection and clear boundaries still work together.

Connection & relationships

Notices peers and joins their play
Recovers from many routine separations with support

Communication

Keeps a brief back-and-forth conversation going
Asks who, what, where or why questions
States a first name and is understood by other people most of the time

Thinking & play

Describes an action shown in a picture
Copies a circle after seeing one demonstrated
Responds to a familiar safety warning

Movement & hands

Strings large items with supervision
Puts on some loose clothing
Uses a fork

Try this together

Ask what happened next instead of testing for a right answer
Offer real household work at their scale
Practice feeling words and one calming strategy when nobody is upset

Keep in mind: Speech sound development continues well beyond three. The useful question is whether familiar and unfamiliar listeners can usually understand the message.

Open the official 3 years checklist &nearr;

4 yearsStories, imagination and learning the rules of a room

Four-year-olds are building a story about the world: what happened, what might happen next, how other people feel and what behavior fits each setting.

Connection & relationships

Initiates play with other children and joins rich pretend play
Comforts someone who is hurt or sad
Adjusts behavior across familiar settings with support

Communication

Uses sentences of four or more words
Retells part of the day, song or familiar story
Answers simple questions about what common objects are for

Thinking & play

Names some colors and predicts the next part of a known story
Draws a person with several recognizable parts

Movement & hands

Catches a large ball much of the time
Pours or serves with supervision
Unbuttons and holds a drawing tool with fingers rather than a closed fist

Try this together

Act out a new situation before it happens
Ask open story questions and accept wonderfully odd answers
Provide dress-up, drawing, building and active outdoor play

Keep in mind: School readiness is larger than letters and numbers. Communication, play, motor skills, flexibility, self-care and relationships all matter.

Open the official 4 years checklist &nearr;

5 yearsLonger stories, shared rules and growing independence

By five, many children can hold a plan in mind for longer, participate in group play and tell a more connected story—while still needing help with disappointment and transitions.

Connection & relationships

Takes turns and follows simple rules in a group game
Performs a song, dance or pretend role for familiar people
Participates in a small household responsibility

Communication

Tells a story with more than one event
Answers questions about a shared book
Sustains several conversational turns and notices simple rhymes

Thinking & play

Counts in sequence and recognizes some numbers or letters
Uses basic time words such as yesterday or tomorrow
Stays with a chosen non-screen activity for several minutes

Movement & hands

Buttons some buttons
Hops on one foot
Uses hands with growing precision for drawing, building and self-care

Try this together

Play games with turn-taking, memory, rhyme and flexible rules
Let them complete real tasks without fixing every imperfection
Invite them to tell a story from pictures or from their day

Keep in mind: A child's readiness cannot be reduced to one academic skill. If learning, language, hearing, movement, attention or social connection worries you, bring the specific pattern to the child's doctor and teacher.

The screening calendar

What happens at the well visits

The American Academy of Pediatrics recommends watching development at every visit and using validated screening tools at several specific ages.

Every visit

Developmental surveillance

The clinician listens to your concerns, reviews development and observes the child in the context of health, family and daily life.

9, 18 & 30 months

General developmental screening

A standardized, validated tool looks across communication, movement, problem-solving and social development.

18 & 24 months

Autism-specific screening

This is recommended for every child at these visits, with additional screening whenever a parent or clinician has a concern.

Any time

A concern deserves follow-up

You never have to wait for a scheduled screening age. A specific concern, loss of a skill or a change in the child’s pattern is enough reason to ask.

A screening result identifies whether closer evaluation may be helpful. It does not diagnose a child by itself.

Start with the question

What are you wondering right now?

Is this a milestone—or a deadline?

Start with how to use milestones as a conversation tool rather than a measure of your parenting or your child.

Read milestones without the anxiety →

When will sleep settle?

What changes through the first year, what people call a regression, and what normal can actually look like.

Understand first-year sleep →

Are they ready for food?

Readiness signs, iron-rich first foods, and the allergen guidance that changed within a generation.

Begin solids calmly →

Is this teething?

The signs that fit teething, the symptoms that do not, and what is worth checking with someone qualified.

Sort teeth from illness →

When something feels off

Concern is enough reason to ask

Talk with your child’s doctor if they are not meeting one or more milestones, have lost a skill they once had, or you have another concern. You do not need to wait for the next child to do it first.

Before the appointment

Write down two or three specific things you have noticed and when.
Note what your child does consistently, sometimes or not yet.
If it happens naturally and safely, a short video can show a movement, sound or interaction that is hard to reproduce in an office.

What you can ask for

A validated developmental screen or a closer developmental evaluation.
A hearing check when speech, language or response to sound is a concern.
A referral to Early Intervention, therapy or another qualified specialist when appropriate.

In the United States, families can contact their state’s Early Intervention program directly for a child under three; you do not need to wait for a doctor to make the first call. For a child age three or older, the local public school system can explain how to request a preschool special-education evaluation.

Common questions

The things parents ask between visits

Which age should I use if my child is between checklists?

Use the younger age your child has already completed. A child who is 11 months old would start with the 9-month checklist, then look ahead to one year without expecting those later skills yet.

How do I calculate corrected age after a premature birth?

Subtract the number of weeks your baby was born before 40 weeks from their chronological age. For example, a 16-week-old born 8 weeks early has a corrected age of about 8 weeks. The AAP says corrected age is commonly used through the first two years; your baby's own care team should guide you.

Does hearing two languages slow speech?

No. Children can learn multiple languages, and words across all languages count toward their total vocabulary. A true language difficulty generally shows up across the languages a child uses, so share the full picture with the clinician rather than dropping a home language.

What if my baby never crawls on hands and knees?

Children use more than one path to mobility, and classic crawling is not on the CDC milestone checklist. Still, ask about movement that is consistently one-sided, unusually stiff or floppy, painful, or simply worrying to you.

Is a missed milestone the same as a diagnosis?

No. A milestone checklist is designed to begin a conversation. A validated screen and, when needed, a fuller evaluation provide much more information about a child's individual pattern.

What if my child loses a skill they used to have?

Contact the child's healthcare professional promptly rather than waiting for the next routine visit. Describe the exact skill, when you last saw it and any other change in health or behavior. Sudden severe symptoms or a child who seems acutely unwell need urgent medical care.
