How Babies Learn To Talk

Babies start learning to talk from the moment they hear your voice. Here's how and when babies learn to talk, milestones to look out for in your child’s first three years, and how to encourage their speech development.

How do babies learn to talk?

Babies learn to talk by listening to the voices of people around them, learning what different words mean when you and other family members talk to them, and trying to imitate what they hear.

They'll start with "baby talk," or coos and gurgles, then start to play around with sound-based words like "gaga" and "dada,"

Around 12 months of age, they'll start to use first words consistently, to refer to the people, animals, and objects around them.

Within their second and third years, they'll build their speaking vocabulary at a rapid pace, and start to string words together. All of this happens thanks to continued listening and learning from you!

Baby's speech and language milestones: Through the months

When will baby say their first words?

Every baby is different in their development, and speech development is no exception. So the timing of that exciting milestone can vary from baby to baby.

There are certain age windows, though, where babies usually reach different speech milestones.

If you're concerned because baby isn't reaching certain milestones on this list within the usual window, consult your pediatrician. The earlier baby can get the needed help, the better.

At 0-3 months:

  • Listens and turns towards your voice, as well as other voices they hear
  • Knows parents' and/or caregivers' voices
  • Recognizes when you talk to them
  • Starts to coo, gurgle, and make simple vowel sounds
    • This is to try to imitate your speech, as well as express happiness

At 3-6 months:

  • May try to imitate the spoken sounds you make with their gurgling and cooing
  • Will use lots of "p," "b," and "m" sounds
  • Starts to absorb how people talk to each other
  • Makes lots of different "happy" and "not happy" sounds

At 6-9 months:

  • Around the 6 month mark, starts to babble (use sound-words, like "gaga," "baba" or even "mama" or "dada")
    • But won't use sound-words consistently for specific people, animals and objects yet --- they're just experimenting
  • Recognizes and responds to their name
  • Knows the difference between happy and upset voices
    • And will respond accordingly (smiling at happy voices, getting upset at sad or angry voices)
  • Will start to use tone in their own babbling, to show whether they are happy or upset

At 9-12 months:

  • Starts to understand and respond to basic words (such as "yes," "no," "hi," "bye-bye," "Mommy," "Daddy")
  • Recognizes words for familiar people and objects ("Mommy," "Daddy," "book," "Teddy")
  • May start to experiment with more consonants
    • May start to use more tones of voice
    • Will start to tell you what they want with pointing, other motions and babbling
      • For instance, they may point to or grab a toy, and vocalize to show they want it.
      • Or, they may lift up their arms and look at you to show that they want you to lift them up.

    At 12-15 months:
    • Says their first words!
    • Will use words and sound-words consistently to identify people, animals, and objects around them
    • Although your little one says only a few clear words at this point, they understand the meaning of around 25 words by this age

    At 15-18 months:

    • Responds to, or at least understands, simple requests ("please put it down," "show me your fingers," "give Teddy")
    • Is building their understanding and vocabulary --- will say around 10 words and understand around 50, with more added each month
    • Will use more complex gestures, along with their words, to communicate with you and make requests

    At 18-23 months:

    • Can say even more simple words than before
    • Can point to several people, animals, body parts and objects at your request ("Where is doggie?")
    • May repeat some words (even those not currently in their vocabulary) when they hear you say them
    • Will often leave out ending or beginning consonants of new words

    Around 2 years of age:

    • Will start to string words together in short phrases (2-3 words, such as "bye-bye Daddy" or "want milk")
    • Can follow spoken directions
    • Starts to pretend play, another way to foster language development

    Around 2 ½ years of age:

    • Will string more words together in simple sentences
    • Starts to understand more abstract word-ideas like "now" and "mine,"
    • Starts to learn spatial words like "out" and "in," and feeling words like "happy" and "sad"
    • Continues to rapidly expand their vocabulary
    • Can answer simple questions with words ("where is Teddy?")

    By 3 years of age:

    • Will string sentences together that include subject nouns, verbs, and locations (but not words like "I," "she," "it," and "the")
    • Can answer more complex questions
    • Builds understanding of more abstract words and feelings
    • Starts to use adjectives ("tall," "red)
    • Understands "opposite" words like "big" vs. "little"
