    3 months

    Responds vocally to partner. These early babbles are the first instances of the infant becoming involved in the give-and-take pattern of conversation.
  • 2

    8 months

    Begins gesturing. These gestures indicate the development of intentionality in communications as the infant works to use his or her limited means of communication to elicit a desired effect.
  • 3

    12 months

    Begins speaking first words. At this point, the child has a sufficient lexicon to use words in a meaningful way, without gestures.
  • 4

    18 months

    Begins to combine a vocabulary of approximately 50 words in accordance to word-order rules.
    This milestone marks a turning point away from babbling and towards mature, systematic language use.
  • 5

    2 years

    Begins adding bound morphemes; MLU of 1.6 to 2.2. At this age, with an average vocabulary of 150 to 300 words, the child shows "a complex interaction of syntactic knowledge, limited cognitive resources, ...communicative goals, and the structure of the conversation (Owens, et al, 2015).
  • 6

    3 years

    Sentence structure matures; MLU of 3.0 to 3.3. As vocabulary increases, so does innate knowledge of the underlying grammatical rules.
  • 7

    4 years

    Tailors conversational style to fit specific partner; MLU of 3.6 to 4.7. Increases in cognitive development are reflected in syntactic developments, as the child is able to use words and prosodic features appropriate to a given context.
  • 8

    5 years

    Has learned 90% of language form. While there is definite room for improvement in pragmatic features and the more subtle syntactic features, at this point the child "uses very adultlike language form" (Owens, et al, 2015, p. 66)
  • 9

    6 years

    LIteracy begins as the child learns to read and write. This milestone not only opens up new means of receiving and dispersing information, but represents the ability to think of language in more abstract, symbolic terms.
  • 10

    Adolescence and beyond

    Shows full competency and control of language. Over the first few years of adolescence, language stabilizes, although "semantic and pragmatic development blossoms" (Owens, et al, 2015, p. 66).
