It is still early days for him Amanda! Amy took her first food from my hand after 5 days, but wasn't really happy with coming out for a good few months. You may have to start off slowly and work your way up - start by offering food on your hand (remember to hold still and be patient). Any sudden movements will startle him. Once he is taking food from your hand move the food further and further away so that he has to step onto your hand tin order to reach. That's where having a very long tongue is a pain, lol!
Also, as Carol says, the distraction technique works well, but I think it may be a little too early for that just yet seeing as he only just about tolerates your hand. I personally wouldn't go with the stick approach - I have tried putting a new stick into both Tommy and Monty's vivs and they reacted very negatively and stressed out and I only just tried putting the stick in a place nowhere near them! After that I tried to get Monty out to put the stick in, but he just dropped straight down into his plant and scared me as much as I scared him, lol! Now I always remove them first before making any changes. They accept new things much better if they are put in when the cham is out of the viv. They will eye it suspiciously for a while, but won't stress like they would if they were in the viv when it was added. Monty loves his new stick now, even though he was rather wary of it to start with.
