Cognitive development is the growth and change to our intellect, our mental abilities of thinking, reasoning and understanding.
Young children are atuned to relationships between actions and environment (people, objects, ).
Also, the cultural aspect of a young child plays an important role on his cognitive abilities. And caring adults can provide the base which children can engage in behaviors that promote learning.
As parents we want to engage the child's natural curiosity which is a strong drive to learn and can process sophisticated cognitive skills by setting their environment in a caring and welcoming atmosphere to explore and question, to problem solve, to have the opportunity to learn and know they have the most powerful mind in the universe and they will succeed to their goals.
