It is important to identify the age at which babies begin to babble because a delay may be a sign of hearing impairment. You can ask the mother if the baby babbles by asking, 'Does your baby babble, that is...?'

It is important to identify the age at which babies begin to babble because a delay may be a sign of hearing impairment. You can ask the mother if the baby babbles by asking, 'Does your baby babble, that is...?'

• A. Does your baby play with sounds, for example, squealing, yelling, growling and making raspberries?
• B. Does your baby sometimes mix real words together with sounds that don't mean anything to make pretend sentences?
• C. Does your baby make sounds like hmm or um or unh-unh?
• D. Does your baby say speechlike syllables like ba or ma and repeat syllables as in dada or noonoo?

Answer: (D)

Understanding early vocal development is key: babbling reflects the infant’s ability to produce sound patterns that resemble real speech, which relies on hearing and motor control. When a parent is asked whether the baby says speechlike syllables such as ba or ma and repeats them in patterns like dada or noonoo, it directly checks for canonical babbling. This stage, usually emerging around 6 to 9 months, shows the child is practicing the rhythm and structure of speech, which is important for later language growth and can signal typical hearing development if present. Other child vocalizations don’t target this specific milestone. Playing with sounds like squealing or raspberries is more about experimenting with vocalization broadly, not about producing recognizable syllable patterns. Mixing real words with meaningless sounds and making pretend sentences points to later communicative play beyond the babbling stage. Non-speech interjections like hmm or unh-unh aren’t babbling and don’t indicate the child’s development of speech-sound patterns.
