Developmental milestones refer to the skills and abilities that most children can perform by a certain age. These include motor skills, language development, social interactions, and cognitive abilities. For instance, by 6 months, most infants can sit without support, and by 12 months, they often can say simple words like "mama" or "dada." Nurses assess these milestones during regular well-child visits and provide guidance to parents on how to support their child's development.
