My boy started duck hunting with me at age 5 and big game at 7. Mainly day hunts or multi-day base camp hunts, and this year he is going on his first multi day back country hunt at 11. My daughter, 8, was not interested as much in big game so we have done a few quail hunts where she can talk a lot and pick flowers. Here are my top 5 advise I can give.
1. If they want to go, great. If not wait till they are, no use pushing a kid into it if they are not ready. My kids always wanted to go, so I had to tell them no more than yes.
2. You like glassing and hiking, but the kid may not get it. I always give my son his own binos and tripod to use and he will glass for 20mins and then shoot his sling shot for 20-30 min. back and forth for hours. Stay calm and just be glad your out.
3. I used to get super frustrated with how loud my son was while hiking and I would snap at him for it. Then I just realized I was making him not want to go with me. I ended up just forgetting about the animals and would just enjoy being out with him. To be honest I see just as much deer yelling at him as I do with being calm and stoked to be out side.
4.Bring snacks. Oh man this is the second most important advise that I can give. BRING SNACKS! If you think you have enough, double it. Bring extra water too. My son does not believe in metering water though out the day. 2 hours in and he usually tells me he needs more. I bring my purifier even on day hunts to pump him more water.
5. Last and most important.....It is no longer your hunt, it is your kids hunt/Adventure. It took me years to understand this. If I take my son hunting, especially bow hunting, I no longer expect to shoot anything. I am just out for a fun hike with my son and building him memories. Of all the hunts I had with my father I do not remember the game we shot, just hanging with him. Sooner you realize this the better, makes the hunts way more enjoyable.
Side advise, if you wife is uneasy about letting you go out alone with your kid get an inReach gps/messaging and teach your kid to use it. There is no cell reception anywhere I hunt so this has been key for me.
