I probably should have said that these are neighborhood kids that normally are 7yo and older. They're not toddlers or preschoolers outside with their parents. We live in a neighborhood where kids play outside from sun up to sun down with little to no supervision. Sounds crazy, but I actually love it!
I don't want this really to turn into a debate over whether or not kids should play with guns. Admittedly, I am really uneasy around guns of any type, toy or not BUT if there is a group of ten kids running around outside with toy guns for 12 hours a day playing Star Wars, well they're not inside watching TV, you know? If either of my DDs wanted to play with guns, I'd probably let them, but have a very serious talk with them beforehand.
No, I do not yell at kids for pointing guns at my kids! You can be firm without yelling. I don't take it upon myself to tell these kids what they can and cannot play, but I can make a simple request in order to protect my children. Normally this wouldn't be a problem with DD1 who is good at standing up for herself, but last summer a kid shot her in the face, point-blank (twice!) with a nerf gun and left welts on her face, so yeah, she doesn't dig having a gun pointed at her. Or for DD2 when a kid shot her in the face with a squirt gun, and to DD2 getting water on her face is a fate worse than death LOL.
I also think there's a big difference between kids running by and saying "look, a stormtrooper! (or whatever, I'm so out of the loop LOL Stormtroopers are bad guys right?)" and pointing a gun at DD in passing, and a kid pointing a gun at them in order to intimidate and frighten them. I think that 7yo+ kids should know that that's not cool at all.
I played with guns/swords/battleaxes (hey, I'm the He-Man generation LOL) as a child, but my mother was really strict about not pointing them at people. She didn't even allow us to point at people that we were playing with, which I thought was weird. So I didn't know if my aversion to having guns pointed at my kids was a product of how I was raised, or if it was common in gun play not to point guns at people who aren't involved in the game. That's all!
Thanks for the responses! My girls are generally good at standing up for themselves and making requests for kids to stop things they don't like. The general rule of thumb is ask three times and if they don't stop, tell a parent (as long as the "offense" isn't something dangerous). I'll try to work with them on this one, working with their fears, so that in the future they can verbalize whether they want to participate in gun play or not.
