Infancy
Infant language development has three criteria: form, content, and use.
Form includes components of phonology, morphology, and syntax. They can be seen through vocalizations, true words, and phrases such as "Daddy" and "Daddy up".
Content includes semantics. They can be seen through word reference to salient people and objects such as "mama" or "doggie."
Use includes pragmatics. This is seen when a child listens, observes, and learns from others through social interactions. -

Period: to
Toddler
While toddler language development still includes form, content, and use, they look very different from infancy. Form is where toddlers acquire and refine their phonemes as they witness it through adults. Content is where they begin to progress their language content from novice to expert word learners, as well as expanding their lexicons to be more receptive and expressive. Use is where they learn new language/discourse, functions, and conversational skills, by combining two or more words. -
Period: to
13-18 months
Form: Riley begins to pronounce about 25% of his words with intelligibly. He starts to use negations and has an average MLU of 1.31.
Content: He uses 3-20 words in his everyday speech.
Use: Riley starts showing verbal turn-taking amongst peers. -
First true word
First true word "Mama" is used with intent. -
Period: to
18-24 months
Form: Riley processes spoken language and asks questions with appropriate intonation. He speaks with approximately 65% intelligibility.

Use: Riley uses imaginative and informative language functions with two-gesture combinations. -
One word expressiveness

Content: He is starting to comprehend about 500 words while producing around 200.
Use: Riley starts using two-gesture combinations. -
Two-three word utterances
Utterances progress to two-three words of clear meaning such as "I want ball" -
Period: to
30-36 months
Form: Most of Riley's phonological processes are suppressed and his intelligibility has increased to approximately 80%.
Content: He asks simple questions and understands about 900 words with approximate production being 500 words.
Use: He clarifies and asks for clarifications. -
Asks questions, uses contractions
Asks for help, uses "can't" and "don't" -
Period: to
Preschool
Preschool language development includes a higher sophistication of form, content, and use those previously experienced. Form is where preschoolers make improvements in speech productions, grammatical, derivational morphology, and sentence forms. Content is where they acquire skills by transitioning into an academic environment, and through storybook readings, they acquire new words. Use is where they improve their language with social interactions by using conversational skills and narratives. -
Period: to
3-4 years
Form: Most of Riley's consonants are mastered; he is consistently using contractions and past tense.
Content: He is beginning to narrow the possible meanings of new vocabulary using syntactic cues.
Use: He is beginning to use primitive narratives, and he comprehends indirect requests with nonverbal pointing. -
