I am not trying to pick on you here but just asking some questions in the hopes of figuring out this puzzle. You are indeed brave to tell your story and we are all learning a lot from every new experience we get to share vicariously like this. I respect what you do and know that you are probably learning as you go as well.

I would be getting a new vet too, especially if I was a breeder. I would only use a reproductive specialist who knows what they are doing. You do not sew up an incision w/o anesthesia!!! That is just cruel.

I would not trust your vet either if he assured you prior to breeding that she could easily deliver a standard sized newborn (5 oz) and it turned out he was wrong. There are ways to determine this is advance.

How many generations back did you verify the smallness of the yorkies from the lines of the female and the male? Breeders who seriously, responsibly, professionally, and consistently breeding for tinies (note I did not say "breeding tinies" but rather "breeding FOR tinies") hopefully use a reproductive specialist or at least a vet who is very experiencd and has a lot of breeders in their practice, they breed the size of the dogs down year after year until they KNOW for a fact that the chances of larger puppies or "throwbacks" are very very very small to avoid an increase in the risk of C-section. Because a male or a female is small does not mean that their puppies will be necessarily. You have to develop a program of smaller yorkies to reduce the risk and have more of a chance of getting small babies.

It is also not true that you HAVE TO line breed to do this. The breeders (some of whom are vets) I know who breed for tinies do not line breed.
