So they usually drop the morning nap first, right? I seem to remember this was the case with my older two.
When school starts up in a few weeks, I'm going to have to get her up a little earlier. My son needs to be at preschool at 9, so I think I'll start waking her up at 8. The rest of us are all up at 6:30am during the school year. It's nice to have her sleep in a bit, though, while I'm dealing with breakfasts, lunch, getting my other DS out the door to get the bus.
Perhaps because I'll be waking her up at 8, she'll go down for the night at 8 instead of her usual 9pm.
