Milestones are like signposts that help parents understand what skills and abilities their children should be developing as they grow. They provide a roadmap of expected achievements in areas like speech and language, giving parents a sense of what to look for at different ages. Milestones are important because they allow parents to track their child's progress, celebrate their achievements, and identify any potential areas that may need extra support. Remember, every child is unique, and milestones are just general guidelines to help parents gauge their child's growth and seek assistance if needed.
