Welcome to YT and thank you for saving this baby. I have fostered quite a few yorkies and each one had a totally different adjustment period. My current one that I ended up adopting is Toto. He didn't start to cuddle until about the one year mark! He also barks at children and loud noises. I don't think that is necessarily uncommon for yorkies.
