definitly go with a bb gun. i first shot a bow when i was 3(it was the tiniest bow ever but it got the job done) also when i was 3 i started shootin bb guns. also prolly about the same age my dad would take me in his 2-man treestand and i would sit with him(never saw anything, i wonder why) it was alla mistake cuz now im obsessed with guns and hunting and all that good stuff lol.
