Infant development in the first 12 months: motor milestones and growing skills!
In the first year, infants rapidly develop motor, sensory, and communication skills, with timing that varies from child to child. In the first months, head control improves and social smiles appear; between 3โ6 months, rolling, grasping, and vocalizations increase. From 6โ9 months, sitting, greater mobility, and cause-and-effect play emerge. Between 9โ12 months, upright posture grows, first steps begin, and early daily-life independence develops.
