I recently bought a hand raised and tame IRN.
Now admittedly the breeder has done alot of work with Charlie to the point where he is not really hand shy and will hop onto your hand readily.
Tonight we got some watermelon and I was able to hold it out to him whilst he was sitting in my other hand and he ate some. He also ate some from my wife's hand which is encouraging.
He is definately not sure about me though as he is a lot more flighty and fidgety when I am holding him than when my wife is. For my wife he will sit on her for a scratch for minutes at a time as the pic below shows.

Yes, his wing is cut until he is used to his new enviro and us.
He will not do this for me yet, if I try to scratch him or stroke his head he will wriggle and run off. I guess this is a time thing. He did eat the water melon from my hand which is encouraging.
Now for my question:
When we have him on us he is always trying to get upto our heads and climb on top. I realise this is a bird thing and they have to seek the highest point, but is there anything we can do to discourage this?
We got him on xmas day so have really only had him with us 3 days.
I realise I can search this forum and have done so reading a lot, but find it easier to get direct advice.
Oh, and from the photo, anybody want to have a stab at sex. I realise this is a long way off yet but its always fun to guess.
