Genie! Sounds like you have a very normal baby Yorkie! Toto STILL sleeps a lot and I have her to the vets once a month so I know there's nothing wrong with her!
I think they pretty much adapt to our lifestyles ... it's usually quiet around our house except for TV in every room on all the time! We usually have it on Animal Planet [Toto likes it, so do we!]. When we are moving about the house she is up playing and ripping around but if we are at our computers ... or just sitting ... she is on one of our laps! Not always sleeping ... just likes to be cuddled! Our breeder told us they are "Velcro Dogs" and she was certainly right!
She does take several very "deep" sleeping naps during the day ... just depends on what's going on. However, around 10 AM she insists that I just sit and hold her while she has that morning nap or gets "cranky" almost like a child!! By 5:30-6:00 AM if Patrick is not up yet [and I forget to close the bedroom door] she jumps up on his chest and starts licking his eye!! If the door is closed ... she scratches at it until he opens it! She is an absolute JOY!! Our life revolves around her! I think I said before ... I do documents research in Courthouses, etc. and I take her with me in my bag! She has been welcomed at every courthouse I have taken her to in this country!
Seems that everyone melts at the sight of a Yorkie!!
