Visual fixation is expected in children by which age?

Visual fixation in infants typically develops by around 1 month of age. At this developmental stage, babies start to visually engage with their surroundings, focusing on objects and faces within their immediate environment. This ability is a crucial aspect of their visual development and serves as a foundation for further visual skills, including tracking movements and depth perception that will develop over subsequent months.

At 1 month, infants may not follow objects smoothly, but they can briefly fixate on a brightly colored object or a caregiver's face, indicating their beginning interest in visual stimuli. As they grow, their visual skills become more refined, leading to improved fixation and tracking capabilities. By 2 months, while visual fixation is still developing, infants show enhanced ability to follow moving objects and engage with their environment. Therefore, the milestone of visual fixation is appropriately marked at 1 month of age, making it the correct answer.
