I can't resist the yorkie sleepiness either. Levi prefers to sleep by my feet, but probably every other night, I move him next to my stomach after he falls asleep. And no matter what, if he is still asleep in the morning when I wake up, you can bet I pick that sleeping baby up and put him on my lap so I can hold him and pet him while he is being so sweet and snuggly (he is absolutely wild and crazy and playful if he's awake). I know this annoys him, I can almost hear him saying, "Woman, leave me alone, I'm sleeping."
