Sorry! I was one of the "viewers" who didn't post last night - didn't have time then.
This is a hard one - my little Rexy did the same thing - slept great for a week, would sometimes yip to get up in the middle of the night, but he would go right back into the kennel and back to sleep. THEN, for some unknown reason, after about a week, when he would get up in the middle of the night, he cried and cried when I put him back in the kennel. It might have been when he figured out that Rowdy, mom and dad were all right beside him in the bed.
My solution was to put him in bed with us - not the correct solution, I know, but he didn't ever have an accident in the bed, in fact he stoped waking me up in the middle of the night and started sleeping all night.
We have a king sized bed - so what I did was make a "pillow well" between my pillow and my husband's pillow right up next to the wall (we don't have a headboared). So, there was the wall on one side, my pillow on the other side, my husband's pillow on the third side, and I put another pillow on the fourth side - hence the pillow well. This kept either my husband or I from "rolling over" on him. And I thought if he started moving around to get out of the well, I hoped he would wake me up. Actually though, he stayed in the well - I think he loved it.
I know this solution probably won't work for you - but........
Also, can you put her crate into another part of the house so you can't hear her barking? I used to have to do this with another dog that we had.
If you can't do that, can you put her into a bathroom or a room without carpet with potty pads after she gets up in the middle of the night?
I know it is frustrating, but I promise it will get better!
