The current life span of American citizens is about 78 years old, so I have divided that lifespan into eight categories based off of that number. They are closer together in the beginning because the early years are where we learn the most about ourselves and the world around us. They begins to be farther age ranges as we age because we have experienced more, and new opportunities come more slowly.
- Birth to three years old
- The primary psychology issue at this age is becoming aware of yourself and there are other people around you with whom you interact.
- Four to eight years old
- At this age, children must learn the social aspects of life and must learn how to behave around other people.
- Nine to twelve years old
- This is when children become more acclimated to their environment, so in school they become more focused but still have the challenge of navigating the social aspects of it.
- Thirteen to Seventeen
- At this age, kids mature into teenagers and must come to terms with the fact that they are going to be on their own soon. They must start to learn more from their parents and teachers about how to be on their own.
- Eighteen to twenty-five
- This is when people go off into the real world and become a functioning adult. They must learn new ways of life and how to be on their own for real.
- Twenty-six to thirty-nine
- As an adult, they have settled into their new lives and now start their families so they start the challenge of raising their own children.
- Forty to sixty
- People at this age come to realize that they are on the declining end of their life, they have been alive more years than they have left. Their challenge is making new decisions to change their life style to do what they want to do.
- Sixty-one to death
- This is when people start to retire and many elderly people become depressed because they no longer have a purpose in life. Their kids are all grown up and they have nothing to do all day. Psychologically, they must learn how to adapt once again to a new life style.
Sydney’s Side 
These life stages you have chosen are super interesting to read about! Compared with Erikson’s the age ranges are pretty similar, but not the exact same. Even so, I think your model is an accurate portrayal of his! The life challenges you express in these ranges are all things that people must go through in some way or another during these times. I do, however, think there is more of a distinction between four to eight years old and nine to twelve years old. You list both of the challenges as navigating the social world. I think Erikson would agree, considering he made listed one stage that lasted from five to thirteen years old, almost the same years you did. I’d be interested in learning more about what differences you find during these two stages you listed.
