Welcome to Yorkie Talk. I wrote about new small puppy supplies on my blog:
New Puppy Supplies - Dog Life and Style
An xpen, baby gates, and other containment aids are probably the biggest difference in necessities between a large and small puppy.
I would free feed your puppy for awhile, perhaps up to a year. Sometimes you do have to encourage them to eat, and you do have to monitor them for hypoglycemia. I had to hand feed Max his first year. He would do tricks for kibbles (his idea, not mine
).
Some people will say Yorkies are picky eaters, but I believe this may be trained into the puppies. When people see that the dog doesn't eat right away, they start offering the dog alternatives. The dogs pick up on that and use it to their advantage.
