As children transition from toddlerhood to the preschool years, their communication skills often take a giant leap forward. By age four, many are becoming confident conversationalists, able to share stories, ask complex questions, and understand the world around them in new ways. Understanding typical four-year-old speech milestones can help you know what to expect.

But as a parent, it can be hard to know if your child’s development is on track. As speech-language pathologists, we evaluate several key areas to determine if a child’s skills are age-appropriate.

This guide provides a checklist of typical milestones for a four-year-old, covering what they say, what they understand, and how they interact with their world.

Important Note: This is a list of general milestones. Every child develops at their own pace. If your child has not mastered every skill on this list, it doesn’t automatically mean there is a problem. However, if you have persistent concerns after reviewing these guidelines, an evaluation is a valuable next step. Click here to schedule a free consultation.

What Should My 4-Year-Old Be Saying? (Expressive Language)

Expressive language refers to how your child uses words to communicate. By age four, a child can typically:

• Speak in sentences of 4-5 words or more
• Be understood by unfamiliar listeners (like a cashier at a store) almost all of the time (90-100%)
• Tell stories that stay on topic and have a clear beginning, middle, and end
• Consistently use word endings like ‘-s’ (plurals), ‘-ing’ (actions), and ‘-ed’ (past tense)
• Use pronouns correctly, such as “he,” “she,” and “they”
• Count to 10 or more and name several colors, shapes, and letters
• Share personal information like their first and last name, age, and city
• Ask many questions, including “why,” “when,” and “how”

What Should My 4-Year-Old Be Understanding Of? (Receptive Language)

Receptive language is your child’s ability to understand what is said to them. By age four, a child can typically:

• Follow 3-step, unrelated commands (e.g., “Get your shoes, put the book on the table, and sit down”)
• Answer complex questions like “What do you do when you are hungry?” or “What do you do when you are cold?”
• Understand most “Wh-” questions (who, what, where, when, why)
• Grasp basic concepts of time and the order of daily routines (e.g., breakfast in the morning, bath time before bed)
• Hear and understand most of what is said to them at home and in school

What About Play and Functional Skills?

Play is a crucial part of development and is directly linked to language skills. By age four, a child typically:

• Engages in imaginative and pretend play with more complex scenarios
• Takes turns during games and understands rules
• Shows interest in playing with other children and can cooperate with them
• Can dress and undress themselves

For a broader overview, you can review our guides to milestones for four-year-olds, as well as our comprehensive Ages and Stages handout. According to ASHA’s typical speech and language development guidelines, these milestones align closely with what most speech-language pathologists look for at this age.

Frequently Asked Questions

My 4-year-old still can’t say some sounds correctly (like ‘r’ or ‘th’). Is this a problem? This is very common and often age-appropriate. Some sounds, like /l/, /r/, /s/, /ch/, /sh/, and /th/, are not fully mastered until ages 6, 7, or even 8. The most important factor at age four is overall intelligibility, can strangers understand most of what your child says? If so, minor sound errors are not usually a cause for immediate concern.

What is the biggest difference between a 3-year-old’s and a 4-year-old’s language? The biggest leap is in complexity and clarity. While a 3-year-old is focused on making 3-4 word sentences, a 4-year-old starts telling more detailed stories. Their grammar becomes more adult-like, and their speech becomes clear enough for almost anyone to understand.

What if my child isn’t meeting all of these milestones? Don’t panic. Children develop at different rates. However, if your child is significantly behind in multiple areas on this checklist, or if your parental instinct tells you something isn’t right, it’s worth seeking a professional opinion. Early intervention is the most effective way to support a child who is struggling.

How can I help my 4-year-old’s language skills at home? Talk, read, and play! Ask open-ended questions that require more than a “yes” or “no” answer. When you read books, talk about the pictures and what might happen next. Encourage imaginative play and narrate your daily activities. These simple, everyday interactions are powerful tools for building language.
