WEll, to be honest, my baby was brought home just going on 9 weeks old. Not much of a huge difference . she did well. However, she does suckle on my clothes still. I am home all the time with her too, and believe that this has helped her enormously. These little ones are very needy and are like human babies. Be prepared to spend a lot of time with your new arrival, Make certain the baby is eating often, and bonding well to you. Taking the pup to the vet is very important. Because a lot of times puppies need to be dewormed and will need to start on vaccinations, be weighed and have a health exam. Definately keep your new puppy away from other animals and parks, outside,  until he/she has had all the vaccines. As for potty training I would start with pad training. and with feeding, use a high grade, super pre. Quality food, and free feed, with fresh water. Provide lots of small toys that fit in her mouth. A healthy puppy will want to play. You will also want some safe chew toys, and start out will small bully sticks. 
 Have Fun !
