I raised three kids and never locked up any of my guns. By the time they got old enough or big enough to pick up a gun, They knew better. I would think though that if you have more peace of mind locking them up, then go for it. An unloaded gun is pretty usless however when or if you need it NOW!!!!
Guns were everywhere in my houses growing up. Most of my families houses actually, with kids running around all the time. You have to properly educate and show that firearms are not to be touched without an adult present.
