Might i suggest the following??
1 When the kidlet can walk holding a rifle without using said firearm as a support start with a rifle with no firing pin and teach the very basics of firearm safety (including not pointing it at things you don't want to break/destroy)
2 when thats "done" start with Prone/SingleShot lessons WITH "BLANK" AMMO introduce how to breakdown and clean the rifle at this point
3 when thats "done" swap to LIVE ammo (kidlet should be taller than the rifle at this point)
4 Continue adding new "stuff" like Kidlets own GunSafe/Rifle more "fun" targets and maybe Pistols as desired
N take your Young Citizen to the local Gun Store and do an Introduction. (does a cased/broken down 30/30 fit into a duffle bag with a Tutu??)
