L.E.
You will need to go through 2 weeks, hopefully less,of discomfort. Everytime she gets out of bed immediately put her back in without cuddling her. Eventuly she will see that your will is stronger than hers. No need to raise your voice, just quickly put her back into bed. She doesn't need to go to sleep, but she does need to be quiet and to stay in bed. The morning after she accomplishes this acknowledge her success.
A few words of praise or a simple treat later in the day will reinforce the new behavior. Do this for several days until the new behavior is set.
This new behavior of yours is an important trait for both you and child to learn: your will is stronger than hers. You mean what you say and you expect compliance. When you tell that teenager to be home by 10pm you want to know that she will.
On the other hand you need to remember that you are raising a child to leave home. You want to teach them to make decisions and be a contributer to the world. In this case of the child not wanting to go to sleep, you are teaching them that they don't have to, but that they must comply with your restrictions: in bed and quiet. You are acting for the better good of her and the family.
