I've had dogs that slept through the night on night 2 and I've had dogs that slept through the night after a month. You know, I've used a clock that ticked and placed it by the kennel along with a fuzzy blanket and had a dog sleep the first night. It's all on the puppy. BTW, I sleep 4-6 hours normally so through the night isn't that long for me.
