Co-"Sleeper"?

I HATE my Co-sleeper. Don't get me wrong--I am definitely not ready to move Becca across the hall, and I love having her close, but the the thing is attached to our bed in such a way that she can shake us awake by slamming her legs down on her bed. And she's getting fonder and fonder of doing it. Just when she started sleeping through the night, without needing a bottle, and just when I started to be able to sleep through the night without panicking that she wasn't waking me up every ten minutes, this happens. So then I roll over and rub her cheek (or get up and change her diaper, if it's the first time of the night) and she goes back to sleep. I don't mind it when it's for diaper changes, but last night she wanted it changed multiple times, and only the first was wet. I think she's getting worse at getting herself back to sleep. I know she's getting worse. I still love her, but she's getting worse.
