Sure you can. I taught my nephew not to touch guns at 3. He was very very curious about them and I had to make it very clear. We also drilled it in him not to touch the stove so he didn't get burned. Talking With Your Child About Gun Safety There is no particular age to talk with your child about gun safety. A good time to introduce the subject is the first time he or she shows an interest in firearms, even toy pistols or rifles. Talking openly and honestly about gun safety with your child is usually more effective than just ordering him or her to "Stay out of the gun closet," and leaving it at that. Such statements may just stimulate a child's natural curiosity to investigate further. As with any safety lesson, explaining the rules and answering a child's questions help remove the mystery surrounding guns. Any rules set for your own child should also apply to friends who visit the home. This will help keep your child from being pressured into showing a gun to a friend. http://www.nrahq.org/safety/eddie/infoparents.asp Teaching Grades Pre-K - 1st Depending on the comprehension level of children, some terms may need to be explained. For example, children may not understand what is meant by the phrase, "leave the area." The teacher is encouraged to discuss the concept of "area." It is the room, the house, the playground, the street corner. If the children are not familiar with guns, it may be necessary to explain or show graphically what a gun is. Children may have seen people using guns on television. The teacher is asked to explain that guns on television are toys. People on television shows pretend to be shot and die. It's not real. In real life, in all cases, children must follow the above safety practices when they encounter a firearm. They must understand the potential harm that may occur if these safety practices are not followed. Guns are not toys. http://www.nrahq.org/safety/eddie/whyteach.asp As a matter of fact I just ordered a copy to go over with my nephew.
