?? Not in the US. Kristi Noem, republican governor of South Dakota, has already given her 22 month old Addie several firearms. "Now Addie, who you know, soon will need them, I want to reassure you, she already has a shotgun and she already has a rifle, and she's got a little pony named Sparkles too. So the girl is set up."
But you mentioned 9 year olds. This is a story from about 8 years back:
"A 9-year-old girl at a shooting range outside Las Vegas
accidentally killed an instructor on Monday morning when she lost control of the Uzi he was showing her how to use."

There are a few dozen shootings a year where a 2 to 10 year old shoots and kills a family member or a friend, and this is not likely to change. If you proposed keeping guns from kids, you would be attacked, vilified and likely called a pedophile by conservatives.
