Yes, absolutely!  Children under 18 only need their parent/guardian’s permission, and do not need to be present for the session.  However, what a wonderful gift to give our children, to allow them to become self-aware of their inner being and more in tune with who they truly are, by being involved in their own sessions!  I also prefer to chat with the child about what it is we will be doing and if they’re open to that before the first session.  Getting their buy in will make the process so much better!  In general, if the child can’t/doesn’t want to be present, it’s enough for the parent/guardian to be present on their behalf.  For all children (or all people, for that matter), if they happen to fall asleep during a session, that’s totally fine.  Sleep is the best medicine!
