Have you got a playpen? Aka cardboard. Something that you can fit in with him, so that eventually he'll climb onto you if he's bored enough without his toys
There's a very good taming guide on somebody's website but i've already forgotten who's..
But even if he is scared/nervous about being picked up, do it for 10 seconds one day, 20 the next, 30, 60 etc.. If it feels like he's about to jump just put your other hand infront of the first (fab explaining) to kind of make a path for him to run along.. with your hands.. That way really helped with pip and within, 3 months? She was happy to be held.
