I made some mistakes when mine were little, I tended to snatch them up quickly which freaked them out and made 'em skittish. I was, and still am quite the noobie, but we've been working with them a lot and now they will eat out of just about anyone's hand if meal worms are involved. Slow movements and soft voices cannot be stressed enough. What we did was sit in their house with them while giving them their bedtime snack. We petted them while they ate and they couldn't get too far from us, so they had to tolerate it. I don't think they are ever going to like it, but they are used to it now and not scared of us any more. This took a looong time though, so persistence is the key.
