Keith makes very good points above and I would just like to add the following:
You are going to have to be proactive to counter the B.S. in regard to guns your children/grandchildren are being exposed to on a daily basis in the schools due to the extreme liberal NEA(Teachers Union).
I have 6 grandchildren and each of them has been taken shooting as soon as they were old enough. When they are visiting I show them different guns,explain how they work and what they are primarily used for.
This IMO goes a long way to remove the demonization of firearms they are exposed to in school and the "mainstream news media".
If you have friends that will permit you to educate their children as well by all means do so.

The 2nd Amendment IS an unalienable right.
