To determine if your child is a creator or dreamer, you must watch how they interact with others, how they interact with you, and how they speak about the world and other things in their day to day life. If your child is a dreamer, they will speak about things that are not of this world. They will have an imagination that is so broad and amazing that you will probably find it difficult to follow what they are saying most of the time.
These types of children must be treated in a way that gives them a lot of freedom, and the ability to think and dream and desire as much as possible. On the other hand, if your child is a creator, then they are more scientific and forthright about their wants and needs. They are confident in their abilities and are extremely intelligent as to what they see and perceive around them. If your child is a creator, then you will want to structure their day in a way that helps them feel secure and taken care of.
You must also take note of what they say, take it seriously, and not discount their ideas whatsoever. As a creator, your child must be able to choose the options that work best for them, and you must keep them safe, but also, trust that they sometimes know what is best as well.
