A.W.
Both of my kids went through similar things at different ages even though most of the time they are excellent sleepers. You're lucky this is the first time she has done it. She is just checking the boundaries of bedtime. Don't let her push you. If she is actually scared, like from a nightmare, then by all means go and comfort her. After that, just tell her that it's still night time and she needs to go back to sleep. Leave her in her room and handle it in a matter of fact manner. Don't react like you are asking her to stay in bed. React like it is absolutely absurd for her to think that she can get up when it's not even morning yet! Leave her in her room even if she cries, otherwise you will be doing this for a long time. I don't know what you mean by "getting her" , but if you are bringing her into your room then you are only rewarding her for this behavior. You don't have to be mean about it, but be stern and don't leave any wiggle room in your actions which she might perceive as a weakness and keep trying. Since she has always been a good sleeper, if she knows she can't budge you then she will return to her good old habits!!!
