4-year milestones (CDC): storytelling & friendships

Storytelling and language at 4 years

Around age 4, the CDC describes children as starting to use language in longer, more connected ways. Many can tell what comes next in a well-known story, answer questions like 'what is a coat for' or 'what is a crayon for', and use words like 'me', 'you', 'I', and 'they' correctly. Speech is often clear enough that people outside the family can understand most of what your child says.

You can support storytelling without drills. Talk through your day, ask open questions, and let your child finish their own thoughts even when it takes time. Reading the same books over and over and pausing to ask 'what happens next' gives your child a low-pressure way to practice.

• Tells what comes next in a well-known story
• Says sentences with four or more words
• Answers simple questions about what things are for
• Speaks clearly enough for others to understand most of the time

Friendships and play

The CDC lists social changes at age 4 such as asking to go play with other children when none are around, comforting a friend who is hurt or sad, and avoiding danger like not jumping from a high place. Many 4-year-olds also like to be a helper and change how they act around different people.

Pretend play matters here. By 4, the CDC notes children often pretend to be something else during play, like an animal or a teacher. Cooperative play, taking turns, and made-up roles are how friendships and storytelling grow together. Some conflict over sharing and turn-taking is normal at this age.

Thinking, movement, and daily skills

Other CDC milestones around age 4 include naming a few colors of items, telling what comes next in a well-known story, drawing a person with three or more body parts, and catching a large ball most of the time. Many children can also serve themselves food or pour with adult supervision and unbutton some buttons.

Toilet training often progresses during this period, though timing varies widely. The AAP advises starting when your child shows readiness rather than at a fixed age, and warns that pushing before a child is ready can slow things down. If toilet training is stalling or causing stress, your pediatrician can help.

When to talk with your pediatrician

Milestones are ranges, not pass-or-fail tests. The CDC encourages acting early if you have concerns rather than waiting to see if things improve. Bring it up at the routine 4-year well visit, or sooner if you notice your child loses skills they once had.

Consider asking your pediatrician if, by age 4, your child cannot tell what comes next in a well-known story or use short sentences, ignores other children or does not respond to people outside the family, resists dressing, sleeping, or using the toilet, or speaks so unclearly that strangers rarely understand. Trust what you see day to day, and let your pediatrician make the call on next steps.

Quick answers

My 4-year-old still plays mostly alone. Should I worry?

The CDC notes that many children at age 4 ask to go play with other children when none are around, but children vary and some warm up to group play more slowly. Watch whether your child ever joins in, makes eye contact, and responds to other children. If your child consistently ignores other children or does not respond to people, mention it to your pediatrician.

My child cannot tell a story yet. Is that a problem?

Telling what comes next in a well-known story is one CDC milestone for age 4, but it is a guidepost rather than a deadline. Keep talking, reading, and asking open questions to give your child practice. If by 4 your child cannot use sentences of four or more words or is hard for strangers to understand, ask your pediatrician.

Should my 4-year-old be fully toilet trained?

Not necessarily. The AAP advises starting toilet training when your child shows readiness rather than at a set age, and timing varies widely from child to child. Pushing before a child is ready can slow progress. If toilet training is stalling or causing stress, talk with your pediatrician.
