Developmental milestones are specific skills or behaviors that most children can achieve by a certain age. These milestones help parents and healthcare providers track a child's growth and development in areas such as motor skills, language, social interactions, and cognitive abilities. Common milestones include sitting up, walking, talking, and playing with others. Monitoring these milestones is important because they can indicate whether a child is developing typically or may need additional support. Each child develops at their own pace, but significant delays in reaching these milestones may warrant further evaluation by a pediatrician or other specialists.
