You definitely do not want to get her up in the middle of the night when she gets up. The first time you do it will make it that much harder to break her of the habit. She will think, "Hey, when I whine they get me out, so I will whine some more." You will have a couple of sleepless nights, but it will be worth it in the end. It's better than going weeks on end with not much sleep. Trust me I've been there. The key is to
just ignore her. Hope this helps.
