Congratulations on your new little one!
I would suggest buying a small blanket to give to your breeder, prior to bringing your baby home. Ask the breeder to put the blanket in with the mother pup to absorb her scent. Then put the blanket in your new babies bed.
I did this for Yazmin before bring her home and I believe it really helped her adjust to her new surroundings. She never cried once from being taken away from her parents or siblings. She carried that blanket around for almost a year!
