As your toddler grows, their vocabulary expands at an amazing pace. Between the ages of 2 and 4, you should notice your child picking up new words every day, stringing together sentences, and talking more confidently. But how do you know if their speech milestones are developing on track?

It’s very common for parents to wonder whether their child’s pronunciation is typical for their age. In this blog post, we’ll show you which sounds children usually master by 4 years old so you can understand the normal stages of speech development and recognize when speech therapy might be helpful for your child.

The Building Blocks of Speech Sounds

Learning to speak clearly is a complex motor skill that takes practice! Speech sounds develop gradually as a child’s mouth, tongue, and coordination skills mature. Children first master easier sounds that require simple mouth movements (like p, b, m), and later move on to sounds that take more skill (like r, s, th).

The exact timing of when your child should be able to make these sounds varies from child to child. Speech-language pathologists (SLPs) use developmental charts to identify general patterns and help determine if your child is on track, or if they need extra support to reach these important milestones.

Sounds Most Children Can Say by Age 4 

By the time your child turns 4, you should understand most of what they say. A helpful guideline to remember is that people outside your family should be able to understand your child’s speech about 75% of the time.

By this age, many children can correctly pronounce the following sounds in most words:

  • B – “ball”
  • D – “daddy” or “dada”
  • F – “fun”
  • G – “go”
  • H – “hello”
  • K – “kitty”
  • M – “mommy” or “mama”
  • N – “no”
  • P – “puppy”
  • T – “table”
  • W – “water”
  • Y – “yes”
  • NG – “going”

Common Speech Patterns in Toddlers

You may still hear some cute mispronunciations—that’s normal! As children learn to coordinate their lips, tongue, and breath, they often use predictable “shortcuts” to make these sounds. For example, some kids may say “tat” instead of “cat” because it’s difficult for them to make the hard C sound.

Certain sounds, such S, R, and TH, typically develop between the ages of 5 and 7. This means that, if your child says “wabbit” instead of “rabbit” or “thoup” for “soup,” they’re still within the normal range for age 4.

These are normal speech patterns at younger ages and gradually fade as your child’s speech skills mature. Most of these types of patterns should begin to disappear by about age 4 ½ to 5. If they continue beyond that point, it’s a good idea to ask our SLPs for an evaluation.

When to Be Concerned About Speech Clarity

Every child develops at their own speed, but there are some signs that may suggest your child needs extra support. Our experts would recommend that you schedule a speech evaluation for your 4-year-old if they:

  • Can only be understood by family members (strangers understand less than 75% of what they say)
  • Omits sounds from the beginnings or ends of words
  • Replaces most sounds with easier ones (for example, K or G becoming D or T)
  • Seems frustrated when trying to communicate
  • Has a history of frequent ear infections or hearing issues
  • Uses mostly vowels and few clear consonants
  • Struggles to imitate new sounds even after you model them

What Parents Can Do at Home to Build Speech Skills

Even outside of therapy, there are many ways to support your child’s speech development at home:

1. Model the correct sound, but don’t overcorrect.

If your child says, “tat,” simply repeat, “Yes, cat! I see the cat.” This reinforces the right sound naturally.

2. Read aloud every day.

Books expose children to new vocabulary and sound patterns. Point to pictures and emphasize words that contain the sound you want to improve.

3. Play sound-based games.

Try “I Spy” using beginning sounds: “I spy something that starts with buh – ball!” You can also sing nursery rhymes together or teach silly tongue twisters.

4. Use mirrors.

Let your child watch how their lips and tongue move when making certain sounds. Kids love imitating “speech faces.”
