Mental Leap 10 – The World of Systems

With the tenth leap, 75 weeks after due date, or more easily said, 17 months, your toddler gets the new ability to perceive and handle “systems.”

He is now able to see clearly over the world of principles. He no longer applies principles as rigidly as before. He is able to adjust his principles to changing circumstances.

He also starts to understand that he can choose how he wants to be:

  • honest
  • helpful
  • careful
  • patient
  • etc.

Or, he could choose to be just the opposite. From off this age you can see him develop the earliest beginnings of a conscience by systematically upholding his values and norms.

We adults use the term “system” if the parts it consists of are interdependent and function as a whole. There are tangible examples, like a grandfather clock that needs winding, en electrical network or the human muscle system. There as also less tangible examples such as human organizations.

To name just a few examples:

  • take the scouts
  • the family
  • the drama club
  • the police station
  • the church
  • our society
  • our culture
  • the law


You can’t spoil babies, but you can toddlers! By understanding what is happening inside that little head of your newly formed toddler – and remember, they are pretty savvy – you can shape the future behavior of your toddler and set values and norms that will carry him through life.

To learn more about how to do so, be sure to read the new, extended edition of The Wonder Weeks.
