I have a new yorkie puppy too. My older girl is doing better with her every day. They have started playing together and she seems to not be as jealous of the new addition. We really tried to show her as much attention as we always did and included her in with the new puppy as much as possible. My vet says it takes time and to still not trust them totally alone for quit some time. As for sleeping I was lucky there. I have her in a play pen with puppy pads and she slept all night by the 4th or 5th night. On Saturday she even went over to the puppy pad in the xpen and went pee-pee on her own. I was like a new mommy, just thrilled. I had to call and tell my best friend and my brother the news. Hang in there and I'm sure it will only get better with time.
