Milestones are significant points or events in a process or journey that mark progress or achievement. They can be used in various contexts, such as project management, personal development, or education. For example, completing a major task or reaching a specific goal can be considered a milestone, helping individuals or teams track their progress. In the context of child development, milestones refer to key skills or behaviors that children typically achieve at certain ages. These can include physical abilities, like walking or talking, as well as social and emotional skills. Monitoring these milestones helps parents and caregivers understand a child's growth and development.
