I grew up on a farm. In my family each of the boys got a shotgun on Christmas following their 9th birthday. That Christmas we already knew what the big gift was.
At 9 years old I thought nothing of going rabbit, squirrel, quail or dove hunting by myself after school or anytime I was bored. My parents never gave it a second thought either. It was just the way things were. I just had to be home in time for dinner.
I have 3 sons of my own now, and have times changed. We still hunt frequently together, but they never had the freedoms I did.
BTW, I still have my first shotgun and still hunt with it. I bet most of you have never even seen a bolt action shotgun... I can still chamber a round quick enough to get 2 shots at a covey of quail. That is a result of decades of carrying that gun. It points like my finger.
