Developmental milestones are specific skills or behaviors that most children can achieve by a certain age. These milestones are categorized into different areas, including motor skills, language, social skills, and cognitive development. Tracking these milestones helps parents and caregivers understand a child's growth and identify any potential delays. Each child develops at their own pace, but there are general age ranges for achieving these milestones. For example, by 12 months, many children can say a few words and may start to walk. Monitoring these milestones can provide valuable insights into a child's overall development and well-being.
