4 Development Stages in Children

For today's post, I am showing you one of Jean Piaget's theory's. This theory is about 4 Development Stages in Children (as shown in the title). Jean Piaget has done this experiment from stage 1: (0-2 years), stage 2: (2-7 years), stage 3: (7-11 years), stage 4: (11 and older, until to 19 years old).  On top ↑ is an image of the 4 stages in the theory (. Also below are more depth information about the stages.

What I've learnt: In the first stage the babies (little children) would get more sensitive like moving objects and sucking them. In the second stage, I didn't know that they would often use "why?". For the third stage, they use more thinking as they get older. For the fourth and last stage, they have the ability to use hypothesize (brainstorm).
