How much sleep is too much

[Kasterborous]

I don't know if this is the right place for this, but our DD seems to be sleeping too much. She's 19 months old and usually has a two hour nap early afternoon after her lunch, then we usually have to wake her up,goes to bed around 7pm and it's not unusual for her to not be up until 9am. We woke her up at 9.40 this morning. She's fine when she's up, full of energy and constantly on the go, I have always needed lots of sleep, so is she like me or is there something wrong with her?

if she's fine and energetic when she's up I don't think there is anything wrong (am very very my dd is the opposite!)

Just think though minipie when she starts school I will have to drag her out of bed, kicking and screaming. If I it's any consolation she doesn't always sleep that well, and wakes up at any slight noise.
