The things I have done to help him learn that I am a safe human, reinforcement training:
* Taking treats from my hand (took about 2 weeks)
* Sniffing my finger then taking the treat from the other hand.
* Offering said finger at a "safe" distance, and only moving it closer if he seems interested. If he looks away, I say "no? ok" and withdraw my finger.
* "Gimme 5" trick, so he touches my hand confidently to get a treat.
* Mealtime interaction, starting with a meow
