In this episode, we dust off Dr. Kim's dissertation and dive into the world of secrets and secret hiding places. Not only do young children understand the concept of secrecy and have a fairly complex view of what it means to have a secret, they also designate spaces for play and spaces they retreat to when they want to be alone. And they go to great, magical lengths to ensure that no adults or big siblings are allowed!

Did you have a secret hiding place when you were a kid? Do you have one now? Leave us a voice mail about it on Speakpipe--we might just feature you in the next episode.
