Sleeping in

Does anyone get to sleep in anymore? Patrick and I used to take turns sleeping in on the weekends while the other got up with the little one. Now, our little one should be able to get up and watch Television without one of us in the room. Does this actually happen? NO!! She comes in and wakes us up. "Mommy, is it morning? It's time to get up!" We have tried the stay up late and hope she sleeps in, but that doesn't work. We've tried making the room as dark as possible, that doesn't work. I guess my child will always have an internal clock set for 7am! This is always the case on the weekend, but come Monday morning she doesn't want to get up! Go figure.
