LadyJane: Thank you for your reply. In previous post the 2.8lbs mom wasn't a typo at all as I said (sorry for the confusion), but my upcoming puppy now is from a different mom who is 5lbs and same dad who is 3lbs.
 
I don't think you are being hard on me, it's an honour that someone cares so much and tries to prevent any issues I might have if I don't choose wisely! 
I honestly did my research and getting a puppy whatever breed and size can always be a risk. There are a few other breeders but I turned away as they bred many different breeds and wanted one that dedicated to yorkies only. This was the ONLY one.  
I do prefer a smaller one (under 5lbs and above 2.5lbs which the breeder is aware of) for myself but again this is an estimated size based on bloodline and parents. There is always a chance my future puppy turns out to be a moose (or a mouse)!  
I don't know exactly when I can bring her home. 12 weeks is fine as long as I can visit her regularly
