Welcome to YT!! So glad you are asking questions before you get your little one home. I hope the breeder will hang to him for you for a few more weeks. Actually, staying with his momma & littermates longer, should make potty training & a lot of other things much easier on your family. While, I know you're anxious to bring him home, the wait will be worth it.
I would avoid anyone sleeping with your puppy - there are so many dangers involved or potty accidents
When you get your lirrle guy, you'll have to sign him up for our Little Gentleman's Club, you can do so on this thread:
