When we talk about how people grow and change, psychologists point out some important stages we all go through. Here’s an easy way to understand these stages:

1. Infancy (0-2 years):

   • This is when babies create strong bonds with their caregivers.
   • They also learn how to move their bodies better.
   • Think about all those little baby milestones!

2. Childhood (3-12 years):

   • In these years, kids start to learn how to talk and make friends.
   • It’s a fun time of exploring the world and picking up new things.

3. Adolescence (13-19 years):

   • These are the teenage years!
   • Teens begin to figure out who they are and want to be more independent.
   • It can be a time with lots of emotions—sometimes happy, sometimes sad.

4. Adulthood (20+ years):

   • Now, adults focus on building relationships and starting their careers.
   • It’s about creating a life and handling responsibilities.

Each of these stages helps shape who we are. Two important thinkers, Erik Erikson and Jean Piaget, studied how we grow. Their ideas show how we develop and change as we go through life!
