If your breeder is a responsible, ethical breeder, I'd have no hesitation in waiting for the pup. That type of breeder has already done, and will continue to do, a great job socializing the puppy and preparing them to be great adults. I'd actually prefer a slightly older puppy myself, as I like a bit of a head start on things like potty training.
If you aren't absolutely confident that this is a fantastic, ethical breeder (and there are a TON of resources here on DT that can help you figure that out), I would be looking elsewhere and asking for my deposit back. Having purchased an older pup from a less responsible breeder, missing out on the critical socialization period has long term consequences that I would never choose to deal with again.
