At seven months, babies go through a series of developmental milestones that are essential for their growth and development. These milestones include physical, cognitive, and social-emotional changes.
Physically, babies at this age are becoming more mobile. They may start to roll over, sit up, and even crawl. They are also developing their fine motor skills, and they may start to pick up small objects and put them in their mouths. Cognitively, babies at this age are becoming more aware of their surroundings. They may start to recognize familiar faces and objects, and they may even start to imitate sounds and gestures.
