Congratulations, I remember reading on a vet site that pups sleep somewhere between 15-20 hrs a day and couldn't find it but did find this.

Of course that will taper off with each new week to 10 days of their life.
Enjoy and can't wait to see pictures. I love to see bright clear eyes on a puppy and if she's happy and playing after a nap these are all good signs!
