Welocme to YT.
I have not had 2 small yorkies before, but....I did get 2 weimaraner puppies at the same time, same breeder...WHEW!!! They drove me nuts and never again...Not with a weimaraner. They are BIG dogs and eat EVERYTHING. Like TILE FLOORS!!!
I think you will be fine with 2 small yorkies. I have a friend that got a male and female, just a few weeks apart 15 years ago. They did great. Played together, learned together.
Just make sure you keep them on a schedule and love them lots...
