My son is only 21 months but I've already started working with him in identifying his animals. He picked up on the typical animals with no problem. (cat, dog, bird, elephant, monkey, etc.) Now he's saying deer, elk, turkey and bear. I'll sit and watch the hunting shows on TV and he's right there next to me naming the animals. He's even started picking up on the elk and turkey sounds and can identify them when he hears them.
I take him scouting from time to time and I'm really looking forward to next year already when I hope to take him out on an actual hunt. Most likely we won't see anything but I guess you never know. I'll just be happy to get him started on what hopefully will be a lifelong passion to hunt.
