Sleep - it does a Mommy good

Emma has been getting up at 6:00 (in the morning!) these past couple of days. That's practically the middle of the night for me. And I had gotten so used to her sleeping until 7:00 or 7:30. In fact, I'd made a little "rule" in my head that I don't get her out of bed until 7:00. Don't worry, she's not in there screaming her head off - if that were the case, I'd definitely get her out of bed! She's really good about playing in her crib when she gets up...as long as she has her pacifier. Does anyone know how to get a 16-month-old to sleep in?! I think she's been off since we haven't spent a weekend at home since April. And she's started taking horrendously long naps in the afternoon. I guess she gets her sleep then. Hey, maybe I should try that, too!
