Which developmental milestone typically appears earliest in infancy?

• A. Making cooing sounds
• B. Rolling over from back to front
• C. Using a pincer grasp
• D. Babbling consonants

Answer: (A)

In infancy, the first clear milestone is the emergence of vocal play, known as making cooing sounds. These vowel-like noises typically appear around 2 months as babies begin to explore their voice beyond crying. They mark the start of intentional sound production and laid the groundwork for later language, such as babbling with consonants. The other milestones come later: rolling over from back to front usually happens around 4–6 months, pincer grasp develops around 9–12 months, and babbling with consonants appears after that, roughly 6–10 months. So cooing is the earliest milestone because it represents the initial stage of purposeful vocalization in infancy.
