I too have an 8 week old puppy. I highly recommend crate training for the night time. I won't be bringing Nelly up to the bedroom, as upstairs is out of bounds for the time being. Although Nelly has been a good girl so far at night I do keep sneaking down to spy on her as I am hearing imaginary whimpering and the same in the day when she has her nap on her cushion even though she is silent! Sleep deprivation is a terrible thing though. It won't last forever - be strong and don't give in with the whimpering.
