Kids want the same thing out of hunting that we all do: great memories and a positive experience. The key to success is remembering that this looks different from your child's perspective than it does from yours or another adult's. When taking young children, remember that you are really taking THEM, rather than them accompanying YOU. Once they lose interest or get unhappy with the situation, it's time to change things up or head into the Waffle House.
Don't expect a perfect hunt with a young child. Some can sit still and quiet for 15 minutes, but most can't. If it's miserable for them, or you get upset with them for causing you to miss a chance at a coyote, they will not learn to LOVE it, which is your ultimate goal, right? Keep it in perspective. Just spending that one on one time with them, sharing something you love, lets them know that they are important to you. Don't spoil it by letting them think for one minute that it is more important than them or their feelings.
Get them a call they can blow and let them engage with you at home as you both practice your 'callin'. Above all, remember that positive reinforcement will help turn them into a life long hunting buddy. When they're old enough to start teaching technique, use the C.P.R. method (coaching technique) instead of straight criticism. (C = Compliment: Find a specific thing they are doing right and compliment it. "You did a good job using your eyes to scan instead of turning your head." P=Positive Correction: In making a correction, put it in a positive statement. For example, instead of saying "Don't move so much", say, "When we're on a stand we sit very, very still so the coyotes won't see us." R=Reinforcement: Model what you want them to correct, and then get them to try it, offering a smile and a 'good job' when they do it.) Most of all, young kids want to please their parents and be LIKE their parents. Kiddy camo is a great ego boost for you and them in that regard, and helps remind them that they are doing something special.
During Kiz Jr.'s early days Kizmo was a turkey FIEND. Life changed at our house during turkey season, as everything revolved around it. By the time Kiz Jr. was 3 or 4 Kizmo was eager to share the fun with him, but we agreed that he would not take Kiz Jr. until he, himself, had gotten his limit, or met whatever goal he had. (100 inches of beard in one season, finishing a Grand Slam, Royal Slam, or whatever.) That way, once the father-son hunting started, it was all about the son. This allowed Kizmo to not be quite so stressed if his little guy couldn't sit super still, or got hungry, or nature called.... As Kiz Jr. got older and more able to sit still, etc. he was eager to go because Kizmo had made it fun and not stressful when he was younger. Fast forward several years. Kiz Jr. shot his first turkey at age 9, and when he was 13 he called in a double for himself and Kizmo. That was the full circle of what Kizmo had hoped to accomplish. (Training him to enjoy it, as well as teaching him how to be successful at it.)
Kiz Jr. will soon be 16, and has hunted all his life, harvesting deer, hogs, turkeys, foxes, fox squirrels, crows, dove, bobcats, and coyotes. It all started with those short little turkey stands as a kid, when Daddy was not stressed to have a perfect hunt, realizing that just being together in the woods, and 'hunting' was good enough. He taught little lessons, not big ones, and just enjoyed spending the time with Kiz Jr. At the end of the day, that's what it's really about.
In some of Byron South's earlier videos he's hunting with his children when they were younger. If you can find some of those they would be great for your child to watch with you, prior to actually going out. Kids naturally like to watch other kids, and will pay more attention to them than they would to adults, and will try to imitate what they see other kids do.
Enjoy every minute of it, and don't blink! There will be plenty of time for 'perfect' stands, sitting still and not talking before you know it. For now, enjoy the squirms and the squeals. They don't last.
