I don't think puppies should ever have access to any carpet at all. Once they have peed on carpet, then it's ingrained in them for life. They will always soil a carpet given the chance. I would only let them in a room that has no carpet or rug, for playing. The lady I got my first two from has a bedroom set up for the puppies when they get to be two or three months old, and have learned what a pee pad is all about first.
I hope you post pictures of those little cuties.
