Babies start to develop a certain image of what to expect. A newborn will begin to recognize familiar faces as she sees them, but when the person leaves, she isn't able to remember that person's face. When the baby is nine or 10 months old, she'll see something that belongs to that favorite person and become excited. She'll be remembering that person in their absence. Throughout the first 18 months of life, your baby will show what he or she remembers through behavioral response, such as laughing or smiling.
Unique things do stand out in a child's mind.
As children get close to three years of age and develop better language skills, they can talk about past events even more elaborately. You may be surprised how far back they can remember. Although kids may remember past events, they often don't volunteer details.
