Also, we wound up using baby receiving blankets because we were bad at potty training our first puppy and he was a slow learner (I'd like to think that had a tiny bit to do with it lol) so we could just throw them in the washer when a few were dirty and always had extras for a bed.    
Good luck!! | 
 
  An extra couple of weeks can make a big difference in their social development. If you have ever seen the interaction between the mother and the puppies, you wold understand why.  They teach them so much about how to play nice and to know their place.  You get a puppy that knows not to chew on you, and they are easier to housebreak. 
The social development starts around 8 weeks of age.  Up  until that time, the mother just feeds them and cleans up after them.  At 8 weeks she starts to teach them and scolds them if they do wrong.  It's amazing to watch.
