Just like others have said, leaving a shirt or something you have worn, so Bailey can snuggle in it and have your scent. I just watched my cousin's little yorkie last week. She left a shirt she was wearing. He would lay on it, and curl up in it. after a day or so, he was playing with my crew. It sure helped.
