Advice on 6 week old pups?

Inuyasha 😍 • Swamp Monster 👾

so I currently have a 16 week old puppy that I adopted from 8 weeks. I was just informed that there are two six week old puppies that are being neglected so I am taking them into my care. I'm not really sure what to do with puppies that young so any advice would be great. thank you!
