Insomnia

So, my 2 1/2 year old has some insomnia. She goes to bed between 8 and 9, but she doesn't go to sleep until close to 11pm. She still gets up at 8am, usually, but wants to nap longer in the afternoon. I love the long naps, but I'm sure they aren't helping her nighttime sleep. She has a nightlight. She usually listens to Mozart or Junior's Bedtime songs to help her settle in. I on the otherhand am not having trouble falling asleep.......
