My DS is 3.5 and he got his first toy gun at christmas time. I had decided that we personaly will not buy them but it's hard if someone else gives it to them. He actually copies Andy from Toy Story as he dresses up and plays Cow boys alot.

I have taught him to shoot at objects and not people, he is never allowed to aim the gun at a person. I don't like the idea of toy guns but if handled correctly I don't think they will harm them.
