Developmental Milestones at 3, 4 and 5 Years

How to read this

• The 2022 CDC checklists list skills that most children (about 3 out of 4 or more) show by that age. So a missing item is a reason to look closer, not a diagnosis.
• Children who were born early, are learning more than one language, or have had a lot of change recently may follow their own timeline. See the developmental variation guide, and the milestones guide for birth to 3.

By 3 years

• Social: calms within about 10 minutes after you leave at drop-off; notices other children and joins in play.
• Language: has short back-and-forth conversations; asks who, what, where or why; says what is happening in a picture (running, eating); says their first name when asked; is understood by others most of the time.
• Thinking: draws a circle after you show how; avoids touching hot things when warned.
• Movement: strings large beads; puts on some loose clothes alone; uses a fork.

By 4 years

• Social: pretends to be someone else in play (a teacher, a dog, a superhero); asks to play with other children; comforts someone who is hurt or sad; likes to help; avoids some dangers, like jumping from a high place; adjusts behavior to the place (quieter in a library, louder at a playground).
• Language: uses sentences of four or more words; says some words from songs or stories; tells you at least one thing that happened in their day; answers simple questions such as what a coat is for.
• Thinking: names a few colors; tells what comes next in a familiar story; draws a person with three or more body parts.
• Movement: catches a large ball most of the time; serves food or pours water with an adult watching; unbuttons some buttons; holds a crayon between fingers and thumb, not in a fist.

By 5 years

• Social: follows rules and takes turns in simple games with other children; sings, dances or acts for you; does simple chores like matching socks or clearing their plate.
• Language: tells a story with at least two events; answers simple questions about a book you read together; keeps a conversation going for more than three back-and-forths; uses or recognizes simple rhymes.
• Thinking: counts to 10; names some numbers between 1 and 5 when you point; uses time words like yesterday, tomorrow, morning and night; pays attention for 5 to 10 minutes to an activity like story time (screens don't count); writes some letters of their name; names some letters.
• Movement: buttons some buttons; hops on one foot.

Everyday ways to help

• Talk, read and sing every day, in whatever language feels most natural at home.
• Pretend play, playgrounds, art supplies and simple board games build many skills at once.
• Give real jobs: setting out spoons, feeding a pet, sorting laundry.
• Limit background TV and keep screens out of mealtimes and bedtime; see the screen time guide.

When to check in

• Mention it at the next checkup if your child is missing several milestones for their age, or if your gut says something is off. Pediatricians watch development at every visit and can do a quick screening.
• Loss of skills they used to have (words, play, self-care) is always worth raising promptly.
• You don't need a doctor's referral to ask for help. From age 3, your local public school district must offer a free evaluation for preschool special education services, even if your child isn't enrolled in public preschool.
• Vision and hearing checks are part of preschool visits; ask if they haven't been done.
