What developmental milestone is typically achieved at 1 month of age?

At 1 month of age, infants typically achieve the milestone of visual fixation. This refers to their ability to focus on and visually track objects or faces within their line of sight. While their vision is still developing, most newborns can briefly fixate on high-contrast objects, especially if they are within a close range.

Developmentally, this achievement is significant because it marks the beginning of the infant's ability to visually engage with their surroundings, which supports later skills such as tracking moving objects and social engagement through eye contact. The ability to visually fixate also serves as a foundation for further developmental milestones, including improved visual acuity and more complex visual interactions in the following months.
