Cynthia,
This wasn't her first time hunting or sitting and learning. Last year she asked me to take her hunting because her parents don't hunt. She went several times and we only got a glimpse of a deer twice.
She attended a week-long outdoors summer camp with other kids her age and learned to shoot bows, rifles, shotguns, and muzzleloaders. One of her cabin-mates was younger and smaller than her and she was a "pro." She had already killed a deer at age 8.
They gave safety instruction and a mock hunter safety course and test.
I didn't know how she would react after seeing the dead deer and helping to clean it but she made it through just fine.
