B.C.
Kids seem to play like this with out thinking about it. They see shooting aliens in video games and just pretend doing it everywhere else. My son did this too, but he doesn't anymore. When he was 6 yrs old, my husband began instructing him on gun safety and taking him to the range to target practice with the 22. He's a pretty good shot. But now that he knows what a real gun can do (and all the rules regarding safety and why) he doesn't play 'shoot em up' anymore. He doesn't even like playing laser tag anymore. He's had a plastic Harry Potter sword for a long time. In taekwondo he's learning staff, nunchucks and kendo stick (bamboo sword) and he sometimes can spot when a form used in the movies. Nothing makes a kid stop playing around faster than having him do something where he's got to practice it all the time.
