A clinic nurse assesses a 5-month-old infant's language development. The infant's highest level of expected achievement is:

• A. Uses monosyllabic babbling
• B. Links syllables together
• C. Coos when comforted
• D. Uses simple words such as 'mama'

Answer: (A)

At five months, infants are transitioning from pure vowel sounds to producing simple syllable-like vocalizations. Hearing and practicing consonant–vowel sounds during this period leads to monosyllabic babbling, such as single syllables repeated or varied like “ba,” “da,” or “ga.” This reflects a developing ability to coordinate the tongue and lips with vocal tract anatomy and to respond to auditory feedback. It’s a more advanced behavior than simple cooing, which is typical a bit earlier, and far from forming words or stringing multiple syllables together, which occur later. So monosyllabic babbling is the highest level of language achievement expected at this age.
