DS1 has recently started shooting people - making a gun with his hand, pointing it and making shooting noises. He must have picked it up from pre-school (he's nearly 3 and a half) as we don't let him watch anything that would give him such ideas, and I'm not quite sure how to handle it.
My MIL says that DH did things like that at the same age and he hasn't turned out badly , DH says that it's normal for little boys to want to do that, and my mother thinks it's just wrong (but then she had two girls so boys are a bit of a surprise to her).
Is this something that all little boys do? I don't want to make DS1 feel that he's doing something wrong if it's just a rite of passage (and he is having such fun), but I just don't feel comfortable with him going around shooting people and saying that he's going to kill DS2, for example.
I know that he doesn't understand the enormity of what he's saying and pretending to do, but I am struggling to know what to do for the best.
