The following characteristics describe which milestone: follows a moving object with eyes, turns toward a voice, and coos?

• A. Newborn Milestones
• B. Three Months Old Milestones
• C. Six Month Milestones
• D. Twelve Month Milestones

Answer: (B)

These behaviors reflect early social and sensory development typical of about three months. At this age, infants begin to visually track moving objects with their eyes, showing improving eye–hand coordination and attention. They also turn toward voices, indicating growing auditory awareness and social interest. Coos are among the first vocalizations that appear as babies practice communicating with caregivers. Put together, these signs best match a three-month milestone rather than newborn, six months, or twelve months, which show different patterns (newborns have fewer coordinated responses; six months bring more motor skills and babbling; twelve months bring walking and first words).
