I've got some tips for ya;
Be ready to leave when he is.
Don't expect a "quiet" hunt.
Better to set up in a ground blind also to reduce his movement being seen.
Take something to keep his attention if the deer don't pop out right away. (NO VIDEO GAMES PLEASE.) I take this time to show my son how to "whiddle" on a stick safely.
Remember this is "his" hunt, so don't stay out there after he wants to leave for your own reasons.

Have fun and good luck!
