There are 3 brains in the human body; Reptilian (basic survival needs; food, shelter, and/or sex), Limbic (Mammalian; think family/herds), and Neocortex (Human; what allows us such advanced thinking above any other living being). The Neocortex consisting of 2 hemispheres, left & right. The right is the first to develop which allows us to begin communicating (think kicking in the womb). The left activates when the baby begins piecing words together to communicate. The development of the child from this point until around age 7 are considered the most important 7 years of a person's life. This is the foundation of the child's entire life.
