"Babbling" stage of language acquisition in a baby is between :-

Correct option is D

The correct answer is (d) 6 to 8 months old
Explanation:
Babbling is a critical stage in language development where infants begin to experiment with sounds. Around 6 to 8 months, babies start producing repetitive consonant-vowel combinations (like "ba-ba-ba") which is a universal developmental milestone across all cultures.
Information Booster:
● Vocal Play: Infants use babbling to practice the coordination of their tongue, lips, and vocal cords.
● Canonical Babbling: This involves the repetition of the same syllable, which later evolves into variegated babbling with mixed sounds.
● Linguistic Foundation: Though it sounds like nonsense, babbling contains the basic phonetic building blocks of the child's future language.
● Social Interaction: Infants often babble in response to being spoken to, showing early signs of conversational turn-taking.
● Deaf Infants: Infants with hearing impairments also 'babble' using manual signs if exposed to sign language.
Additional Points:
● Option (a): Holophrastic stage – By 9 to 12 months, children typically move toward their first single words.
● Option (b): School age – By 4 to 7 years, children have mastered complex grammar and sentences.
● Option (c): Cooing stage – The period from 0 to 3 months is characterized by cooing (vowel-like sounds) and crying.

So the correct answer is (d)
