Early Vocalization During Infancy

A newborn’s first form of communication is crying.

Changes in pitch, pattern, and intensity signal hunger, sleepiness, or anger.

Crying helps infants survive because its unpleasant sound prompts caregivers to meet the infant’s needs.

From 6 weeks to 3 months, babies coo to express pleasure.

This includes sounds like “ahhh.”

Between 6 and 10 months, cooing evolves into babbling.

Babbling is repeated consonant-vowel combinations like “ma-ma-ma-ma.”

Babbling is also similar across cultures until about 9 months, after which it begins to match the sounds of the baby’s native language.

Around 9 to 10 months, infants begin imitating intentionally, even without grasping meaning.

They gradually produce more complex prelinguistic vocalizations, which are sound combinations that resemble words but carry no defined meaning.

Over time, once familiar with word and phrase sounds, infants start linking them to meanings.

By 12 months, infants who engage in joint attention by following and responding to the caregiver's gaze build stronger communication skills.
