Human Growth and Development / Unit 3 HGD 0363 short lesson, about 20 seconds
Babbling
Captions available
The idea
Babbling, repeated consonant-vowel sounds such as ba-ba-ba, appears around four to seven months and narrows toward the sounds of the languages heard.
In practice
Deaf infants exposed to sign language babbling with their hands in rhythmic patterns.
Where people slip
The misconception is that ba-ba is a first word. Babbling carries no meaning yet; more babbling at six months predicts more words at twelve.
