T.P.
Really sounds like teething or an ear infection. My advice is to try a little oragel on her gums and see what her response is. If she seems soothed, it's teething. It usually works almost immediately. If she still screams, could be an ear infection, especially if she's had a cold in the past week or 2. You can also try giving her a dose of tylenol or motrin at bedtime to see if that helps her stay asleep better. You don't want to do that every night, but you can do it for several in a row if it's helping.
