Avoid the Hype
Kindergarten is a big milestone and it's easy for parents to talk it up too much by saying "Are you excited for kindergarten?" or "This is such a big step for you!" Although it's great to talk about school, you don't want to hype up kindergarten so much that you make him fearful. Instead, talk about the things he will do in kindergarten and help him see that it's things he's already mastered at home.
