Thank you for using Petco Pet Education Center, formerly Petcoach, and congratulations on your new puppy. I'm glad she is playing and sleeping with your 2 older females. While sometimes dog behavior can change over time, there is nothing to say that she will for certain become aggressive with age. As they grow out of the puppy stage, they can try to establish dominance among the other dogs, but this doesn't always happen, and only time will tell what your girls will do. Hopefully, Peaches will continue to leave in harmony with the older dogs.
