Welcome to YT, I am sure you will get lots of advice here, but don't ask if you are not prepared to handle honest answers thrown in with blunt opinions. This site is first and foremost about yorkies, it's their welfare that is taken into consideration by just about everyone that answers a post. To be quite honest I think most of us care more about the dog than the possibility of offending the poster. Therefore it is very upsetting when a new owner comes on here with misgivings about their new puppy, because those are things a responsible dog owner should have checked out before they drove who knows where to pick up who knows what kind of dog.
If you had joined this site before buying your puppy here are a few things you would have known first.
1. You should NEVER buy a toy breed younger than around 10-12 weeks, 12 weeks being ideal. So you got your baby about a month to early that's probably why she is hypoglycemic.
2. If you want to insure you get a good puppy you need to buy from a reputable breeder, which means you do some research about the breeder first then you go to their home to pick her up so you can see where she came from and hopefully meet the parents. You said you saw the dad an other pups from the same litter, where you at the breeders home at another time, or did she have them all in the car.
3. You have a 2,4, and 9 year old, that is a lot on your plate, you must have energy to spare to want to take on the demands of a puppy, let alone a tiny one. May I ask why you wanted a yorkie, did you think it would be a playmate for your children? If so think again, because toy breeds are not the right kind of a puppy for a toddler. If you don't want your puppy to be hurt you will only be able to let your younger two play with her under very close supervision. A 2.5lb dog or even a 5 lb dog is no match for a toddler or a preschooler. They can get easily stepped on, dropped, or squeezed. Puppies have razor sharp teeth so your kids will get nipped and could also get bit. Do you know that many of the snacks you give young children that they often drop on the floor are poisonous to dogs and deadly to toy breeds.
4. Breeding, most of us could go on for hours why someone that knows nothing about the background of the dog, and from the sounds of it yours came from a puppy mill, should not breed. Speaking of breeding, do you have prior experience of owning a dog that has had litter, are you prepared for everything that could possibly go wrong or even right with the birth of a litter.

I am sorry for being so blunt because you are probably a nice person but it is maddening to keep seeing so many people make so many mistakes when purchasing a puppy. I really do hope you stay around and learn all about yorkies and then you will understand why so many of us feel the way we do. Also if you stay around you may come to your own conclusion why breeding is not as appealing as it may at first seem. Good luck with your new puppy.
