I'm happy to meet you! I am new not only to this forum, but have never understood forums, threads etc myself very well. So lets get this party started and learn about our babies AND forum use!! WOOT! And yes, your baby should be quite normal, I wouldn't worry about genetic difficulties, this size yorkie is unusual, but by no means uncommon. If s/he were to suddenly gain weight, haircolor change, etc or you noticed anything drastic that didn't seem like a health issue, then i would advise seeing what type of tests could be ran. your baby should be just fine!
