Why is Anja still on the bottle. She's way past that.
Also, you have created her sleeping problems. Why is she able to get to your bed in the middle of the night? If she couldn't get out of bed, she would go back to sleep. It's normal to wake up during the night. Everyone does it. She needs to learn to get herself back to sleep. She may cry but she'll learn that it's not acceptable to wake everyone up because she's awake She should be put to bed awake. (even at naptime) She's way past being driven to get her to go to sleep. It may take several nights of crying by both you and Anja but she needs to learn.
