This one is not a child but still relevent.
My 65 year old mother was terrified of geese when we got them in December. We explained and showed how to bluff them, pet them (they dont like being loved on as adults) and how to use her foot to bumb their chest IF it got to that point.
Mom asked what would happen if she accidently killed one, I responed that she needed to start a pot of water so we could plug them.
As a child she was scolded for saying the gander bit her and it took several attacks before her dad saw it for himself and removed the bird.
She now helps with every part of keeping them and even sings to the flock.
