What are the expected speech and language development milestones for a baby?


As parents, we eagerly anticipate our child's first words and phrases, celebrating each new milestone in their language development journey. While every child progresses at their own pace, understanding age-appropriate language milestones is essential for monitoring your child's communication skills. In this blog post, we will provide parents with a guide to help them recognize these milestones and what to do if their child is not meeting them. Early intervention can make a world of difference in a child's language development, so let's explore the critical markers and proactive steps to support your child's speech and language growth.

Birth to 12 Months: The Foundation

In the first year of life, your baby lays the groundwork for language development. Key milestones include:

  • Cooing (2-4 months): At this stage, your baby will start to make vowel-like sounds, such as "ooh" and "aah," expressing contentment and engagement.

  • Babbling (6-9 months): You'll notice your baby experimenting with repetitive consonant-vowel combinations like "ba-ba" or "da-da." This is a positive sign of speech development.

  • Response to Sounds (6-12 months): Your baby should react to their name and familiar sounds, indicating they are hearing and processing auditory information.

What to Do: If you have concerns during this period, consider a hearing evaluation and consult your pediatrician for guidance. Schedule a speech and language screening or consultation with a speech-language pathologist.

12 to 24 Months: Emerging Language

Toddlers continue to build on their language skills. Milestones include:

  • First Words (12-18 months): Most children start saying their first recognizable words, often referring to familiar people or objects, like "mama" or "ball."

  • Word Combinations (18-24 months): Your child may begin putting two words together, like "more juice" or "big truck."

  • Understanding Simple Commands (12-24 months): Your toddler should be able to follow basic instructions, such as "clap your hands" or "give me the book."

What to Do: If your child is not yet saying words or combining them by 24 months, it's essential to consult a speech-language pathologist for a language evaluation.

24 to 36 Months: Expanding Language Skills

As your child approaches their third birthday, language development takes significant strides. Key milestones include:

  • Vocabulary Growth (24-36 months): Your child's vocabulary should continue to expand, using hundreds of words by this age.

  • Sentence Structure (24-36 months): Children begin forming longer, more complex sentences, expressing their thoughts and ideas more clearly.

  • Narrative Skills (36 months): Your child can tell a simple story or describe a recent experience.

What to Do: If your child's language development seems significantly delayed compared to peers, consider seeking an assessment and speech therapy to address any potential delays or disorders.

3+ Years: Building Advanced Skills

As your child grows, their language development should become increasingly sophisticated. Milestones include:

  • Pronunciation (3+ years): Your child should be able to pronounce most sounds clearly, with some exceptions for more challenging sounds.

  • Storytelling (4+ years): Your child can tell longer and more elaborate stories, showing their ability to organize thoughts and express themselves.

What to Do: While minor pronunciation issues are normal at this stage, significant difficulties in speech clarity may warrant a speech therapy evaluation.


Understanding age-appropriate language milestones is vital for parents to support their child's communication skills. If you have concerns about your child's language development, early intervention is key. Seek guidance from a speech-language pathologist to ensure your child receives the support they need to thrive. Remember that every child is unique, and speech development timelines may vary. The key is to monitor your child's progress, celebrate their achievements, and take action if you have concerns about potential delays or disorders. Your proactive involvement can make a significant difference in your child's language development journey.
