My babies came from standard sized parents. Their dad was 4lbs and their mom was 5lbs and they ended up just throwing small puppies. If you are going to get a small yorkie, do not patronize those breeders who breed teeny tinies to produce teeny tinies. Look for a breeder who breeds within the standard and happens to produce the smaller ones. There are lots of those breeders out there and those are the ones that produce the healthy tinies.
