Your baby is gathering information all the time, putting it together to form his first pictures of himself, other people, and the world. As you encourage him to explore and learn, you help him gain more information and make sense of it.
Around eight months of age, your baby will be able to have a mental image (a picture in his mind) of a favorite toy (or even of you) for at least a few minutes after it’s not in view. That short term memory is exciting because it suggest that there is some development in the prefrontal cortex of the brain, the area that supports thinking and problem-solving! Playing those hide and seek simple games helps to stimulate that area. Simple fun play helps to build baby’s brain! (ELIOT, L., 1999)
