my son sleeps about 11 hours at night and takes a 1.5-2 hour nap during the day. Its about the same amount of time as your daughter but he's not sleepy when he wakes up at 7:00. Do you think maybe trying to put her down earlier might help her feel more refreshed in the morning? Does she NEED to wake up that early (meaning are you waking her up to get ready for school) or does she naturally wake that early? If you need her to be up at that time, put her to bed earlier (like around 7-7:30). If she has the option to sleep later--make her stay in her bed quietly until everyone else in the house is ready to wake up. My son goes through these little phases where he decides he's going to wake up before the sun and EVERYONE else needs to be awake too--we simply refuse to go to him until 7 a.m. and keep him in his room, but after 3 or 4 days he starts sleeping until his normal time again instead of getting up expecting to play.
