The ba's, da's and ga's that babies start uttering from the six month onwards have a definitive purpose, according to researchers.
These repetitive sounds and speech-like syllables mark the beginning of language development in children, according to researchers. Such nonsensical words lead to the understanding and development of words in the child's vocabulary. Even deaf babies babble just as normal kids but they don't go beyond a point because they can't hear the words others say which they ordinarily mimic.
When babies start to babble, parents and caregivers need to communicate and express more so that babies are encouraged to talk and develop their language skills.
