I started my own daughter out at 3 years old, but it was short lived. Their attention span just isn't there at that age. It wasn't until she was 4-5 years old that she really started enjoying it, and was getting better.
At age 10 i started taking her hunting with me, and started her training on woodsmanship, and tracking. She wasn't squeamish about field dressing deer and elk at all, and she loved climbing mountains with her Papa. But.... she didn't like the idea of killing an animal herself. So as she aged, she still hunted with me from time to time, but she never carried a bow while hunting, or even bought a tag......The all of a sudden Poof! she was off to college, and had her own life going.
She married a great guy i'm proud to call my son, and they gave me a grandson 4 years ago. I'm going to try and get Arlo interested next summer, as he just turned 4 in September. I think he may be ready for an introduction this year, but i'll play it by ear and see how he develops. "Fearsome 4" is a challenge and constant test of wills. We'll see how it plays out, but he's just not ready yet.
