Congrats on picking a breeder and getting on the future puppy list…hope you are successful in getting a pup! 😃 How exciting!
Oh, and regarding the sleeping - I truly think the secret weapon for sleep, besides wearing my pup out before bed, was the snugglepuppy that Lisa (lvoss) recommended. Definitely get one of those!
Liyah had no problems sleeping - I only remember her crying the first 2 nights and then only for 15 or 20 minutes, otherwise, I've always had my full night sleep. So sleepwise, for me a puppy was easy, as was potty training.
