Baby milestones are key developmental achievements that infants typically reach during their first year. These milestones include physical skills like rolling over, sitting up, and crawling, as well as social and emotional skills such as smiling and responding to their name. Each baby develops at their own pace, but these milestones provide a general guideline for parents to track their child's growth. In addition to physical and social milestones, cognitive development is also important. Babies begin to explore their environment, showing curiosity about toys and objects. They may start to recognize familiar faces and sounds, which is crucial for their overall development. Monitoring these milestones helps ensure that babies are progressing healthily.
