I have been taking my 12 yr old son hunting since he was about 4 yrs old. Let them take whatever they want to stay occupoied. the key to keeping them in the woods is making it enjoyable. Don't expect them to stay quiet or still for long periods of time. Be willing to pack up and leave 30-45 minutes before dark if they are ready. take them squirrel hunting where they can walk and see several animals. stand hunting is hard on kids. Most importantly don't get aggrivated or upset with them, when it's time to go it's time to go. enjoy the time together, if they are enjoying it you will enjoy it more.
