Practice your skills frequently and shoot as often as practicable. Them teach your family members the basics of gun safety (the "Golden Rules"), about how to use a shotgun, and establish a place and condition in which to store it. Encourage them to practice with you and to understand and acknowledge the respect one must always pay a deadly weapon. Remove the fear and replace it with discipline. I would not keep a loaded gun in the house until you have done these things, but you will be safer once you have.
Thanks, good advice. That is my intention.
