I've done the puppy thing twice in a yr and a half so things are still pretty fresh in my mind.
I remember getting up every 2 hours for the first week(my guys were home at 8 weeks though) with HUGE improvement after that first week. Two weeks later they were sleeping through the night with the occasional late night bathroom break. Wait another week and you'll see the difference. She seems to be right on track to me.
I never crate trained them though or withheld water. I've actually found that they sleep better with the pack and having access to cool water. My guys were always very restless until I figured out it was because they were thirsty or hot. I had no problems with them disturbing the others at night and they learned very quickly what "no more water" meant. Being a light sleeper helped with getting them outside before accidents.
