I almost said the same thing Deb did, but bit my tongue. People pick up puppies at six weeks and don't have issues, but most "experts" say 7.5 to 8 weeks is about the earliest you want to take a puppy away from it's mom and siblings. The puppy learns a lot about being a dog from it's littermates and mom in those early weeks. It learns how hard it can bite, how to read other dogs, how not to poop where you eat and play. In some states it's actually against the law for a licensed breeder to allow a puppy to be taken home before eight weeks.
It's your pup and you can pick it up anytime you want and it won't bother me at all, I'm just recommending doing a little research on the subject. The puppy will have zero problems bonding with you and your family if you wait until eight weeks.
Good luck!
