While I think what Love said is true, it is not true for all children and may not work for all families. My older son was going to bed at 7:30 and waking up at 5:30. We moved his bedtime to 8:30 and he slept till 7:30. With my younger son, it isn't always possible for us to put him to bed earlier. My older son has Taekwondo from 6:45-7:30 twice a week. If my husband is working that night, I have to take both kids. Also, I used to work and not get home until 5:30 or 6. I had to feed my son before he went to bed, so he couldn't go to bed before 7 or 8.
Larissa, My 7 year-old was having the same problem. We started having him read for 30 min before he went to bed. We didn't change his bedtime, we just have him get ready a little earlier and he reads for the last 30 min. Might work for your daughter. It would give you more time alone after she goes to bed, too.
