I owned a Golden Retriever and a Yorkie years ago; my daughter was under age 6 during this time period. We all did really well together, but I think there are several factors to consider if the big dog-little dog-child combo is going to be successful.
My Golden was older and had gotten the puppy playfulness and mouthing out of her system. She was very gentle and loving, the first in any pack to go belly up in a tiff, even to a smaller dog. If her play had been any rougher it never would have worked; the Yorkie will get stepped on, no matter how closely you supervise.
My daughter has always been one of those laid back kids that didn't jump/run around a lot and was able to learn how to handle a small dog appropriately. (For example, she was only allowed to hold the Yorkie when seated on the floor, so that he wouldn't jump or be dropped from her arms.) When she had friends over, I would put the Yorkie away for his safety.
Overall, I think our little family just required a LOT of supervision, primarily because of the Yorkie. We love, love, loved him so very much. This arrangement worked out really well for us.
Best wishes in making your decision....
