Help!!! My 9 week old Goldendoodle puppy will not stop barking!

We've had Archie for just over a week. The first three days he was so calm, but now he is a wild barking machine. What can we do to curb the barking?! Thank you!

Ditto-- mine mostly barks in her crate because she wants out. I ignore it for 20-30min, but if she's still barking, I feel bad for the neighbors and usually go out and sit with her until she quiets down saying "NO" every time she starts to bark. I'm losing a lot of sleep. LOL
