As they grow, they become skilled at tasks that require greater finesse. Each accomplishment leads to another, slightly more complicated, skill. The early weeks and months of a baby's life are critical to his future learning and development. As soon as you bring your baby home, you can begin to stimulate the learning process. But with practice, their vision quickly becomes more acute.
Babies learn by doing, by reacting to their surroundings at their own pace.
Your baby is instinctively motivated to practice tasks that interest him again and again. He's miraculously and internally programmed to take the logical next step in his development. Your role as parent is key to your baby's learning process. It's your privilege to provide opportunities for him to learn. An infant can't seek out stimulation.
