Object Permanence skill

The skill of object permanence starts to develop as babies reach the end of 7 months. Having the skill of object permanence is reflecting the cognitive (brain) development of the babies. It's represent by Jean Piaget's theory of cognitive development. And at end of 7 months, although babies are still in their sensorimotor stage, they have begin to be aware of their world as their comfort and save environment. At the newborn, babies have no awareness of their surrounding and the object permanence skill do not exist. The object permanence skill is about the awareness that the object/people do exist although they are out of sight. This explains why a baby before 7 months or a newborn cries when do not see his/her mother when it's out of sight. And when babies begin to grap the object permanence skill, they will enjoy playing the peek-a-boo, hide & seek, and treasure hunting game.
Ok, this is about some of the early childhood development theory that I learnt during my uni course. And it's getting relavant and clearer to me when I have a baby of my own. Having Maximus gives me a reflection of all I have studied - the development theory, the psychology in early childhood, behaviour and emotional management, etc. I begin to have a better understand and able to recall/relate to these psycologist or theologiants in early childhood.
Speaking about object permanence, Maximus is getting a whole grasp of this skill. He has started to flip the pillow, search for his favourite "toy" (the remote control) or hidden object. He even look under his cot or table whenever his toys roll under it. Check out Maximus's playing process showing his object permanence skill...

1st panel (on the left): Maximus played with his "toys"(the empty bottle)
2nd panel: "Toy" moved closer towards the cot
3rd panel: Trying to get his "toy" that went under the cot
This is the poof showing Maximus knows and grasps the object permanence skill.
Richrach in reading, when you start your Early Childhood Course later you will be able to understand better the theory as you have benefit from your real life experience. I am sure you will do well...
