I am wondering who would have sold you such a very, very young puppy? Did you buy from a pet store or local breeder? Puppies need a lot of sleep just like a baby, they sleep the majority of the time. Their is a basic rule that Yorkie puppies need to be kept with their mother at least to 12 and better yet 14 weeks of age.
A puppy needs to eat 4 times a day when they are this young. Eventually, you can cut back to 3 times and them at adulthood you can feed twice daily.
