You are correct to wait until your puppy is older to introduce her to the rest of your family. She is way too young and her immune system is not strong enough to handle this . + your aunt has other dogs, your little puppy could easily contract an illness that may kill her, or make her extremely sick , not to mention all the stress of meeting new people , this can double the chance of the risk your puppy getting ill , just by the stress .
Like ohters have stated she is too young to even have left her littermates and mother and needs to only be with you right now, in a quiet environment, there is going to be plenty of time for social occasions in the future, however it is unwise to to this now.
I brought home a 7 week old Shih Tzu who is now 13 weeks . She just went to the vet today, and weighs 4 Lbs. I have kept her inside all the time , along with my Yorkie , Suzi. I have NOT even let Suzi, my Yorkie outside for walks either, only on the balcony with me, it's been triple diget heat though, however, I am not going to risk exposing the new puppy to anything .
New puppies need to be protected, and you can never be too careful. Parvo is serious, and costly if a puppy catches it.
Best wishes to you and your new puppy .
