I would also suggest to you to lok into adopting a yorkie who is at least a year old. That way you will know the dog's temperment, and size. It is really hard to know just how big a yorkie will be as a puppy.
I know that all children are different when it comes to being around small dogs. And yorkie's are also different when it comes to being around children. That is anther really good idea to find a yorkie who is already am adult, but still younf enough to fit in with a family. Sometimes, a rescue group or a adoptiong group will want to see all your family and observe how everybody responds to the dog before adopting out .
Good luck in your search , try to find reputable breeders in your area. Sometimes a breeder looks for anther home after the yorkie is done breeding, then the yorkie is spayed , and ready to be adopted.
