Is it wrong of me to be annoyed hat all my son hears in the background of whatever he's doing is constant gunshot sounds from this game that his father plays? Whenever he's home were constantly hearing the sounds of different kinds of guns going off from this damn game. It's single shot rifles along with semi automatic and machine gun noises. I don't want him picking up on it and repeating the noises when he goes to school, especially with how sensitive the whole gun topic is. And YES he wears headphones, but you can still hear the gunshot sounds clearly even if the tv in the living room is on. Now ive got nothing against guns, we have a few put away in lock boxes, a rifle and two handguns, but he never sees them. I just don't think it's healthy for him to constantly be exposed to the sound of them. He's turning three tomorrow and ive already had to tell him not to try to copy the sounds as he's done it a few times now at home when he's playing. One time he pointed a Lego at his sister and did it. I'm working on getting him to not do that again, but with the constant sound of gunfire from this game in the house I'm worried it's just going to get worse. I'm worried he's going to start preschool and I'll get a call from his teacher that he's making shooting noises and pointing toys at the other kids and it becomes a problem.
