I agree with the person who wrote about not over-analyzing the bonding. It will come naturally, if you let it. The key is to relax and just enjoy.
Don't build up a scenario in your mind about how it should play out. Yorkies, dogs in general, are really perceptive about their humans thoughts and feelings. It would be easy to overwhelm a puppy or dog with expectations to perform or live up to the scenario you envision.
I believe part of the reason my boys are so affectionate is that they know they are not forced into it. I don't hold them against their will (well, maybe jokingly for 5 seconds when I tease them, but they know they are going to be set free immediately, and they come back for more
).
They are also affectionate because we, the humans, are silly with them, and we take care of all of their needs. As I wrote before, the boys also learned how to use affection to butter us up to beg for their favorite things.
