Which milestone is appropriate to observe in a four-month-old during well-baby assessment?

• A. Babbling sounds
• B. Sits without support
• C. First words
• D. Walking independently

Answer: (A)

Around four months, infants begin to engage more with sounds as part of language development. You would expect to hear early vocalizations like cooing and the beginnings of babble, as they respond to voices and try out different sounds with social interaction. This shows growing communication skills and social engagement, which are appropriate for a four-month well-baby check. In contrast, sitting without support requires more trunk control and usually appears around six months; first words typically emerge around the first birthday; walking independently develops closer to a year. So observing babbling sounds aligns with the four-month milestone and indicates typical progress in language and social development.
