Hi D. J, All kids go through the not sleeping at night. Some are worse than others. It's my opinion, but I wouldn't give a child something to make them sleep. I know it's difficult, but sometimes you are better off just taking time before you put a child to bed to read a story, or just talk to them and make them feel a bit more relaxed. Sometimes, even though you think cartoons are good for children to watch, some of them can be very violent. Children don't forget things. My grandson is 5 and he told me one night he was having bad dreams and would wake up afraid. So I asked him to tell me about the dreams and turns out it was something he had seen on T.V. in a cartoon that had him afraid. I explained to him that a cartoon wasn't real it was just for fun and it wasn't anything to be scared of. It was sort of like Chuckie on the Rugrats learning how to potty train. He didn't want to go to the bathroom because he was afraid he would flush down the toilet too. When it was explained in the cartoon he was to big to flush down the toilet, he was ok. That's just an example that made a lot of sense to me because I could see why he would be afraid. Try to find out if your daughter has something bothering her or make it into a game, or just fun. When she senses you are more relaxed, she will be more relaxed. I hope this will help you. Good luck!
