Go to sleep! Please?

It has been very difficult to get Dee to go to sleep this past week. I don't know what the deal is, but last night, Terri rocked her to sleep around 9:30pm and she was back wide awake by 10:15pm. So we ended up driving her around until about 11:00pm until she finally went back to sleep. Then she woke up about 3:40am this morning. She went back to sleep about 20 minutes later, but she was awake at 7:00am again with no sign of going back to sleep. I'm sure this is just a phase she's going through. I've read similar reports from other parents on the internet, but it's about to drive me and Terri crazy.
