Sour Sleep

Our rough day was followed by a rough night. Libby woke up at 2:00, two to three hours earlier than I have become accustomed to. She then woke up every hour until 7. I fed her at 3 and 7, but only gave her the pacifier the other times. Is realizing she's lost the paci waking her up? I hope this is short-lived! (as in, never happens again!)
