It looks like you got great advice. You have to let her cry it out. Secondly, you need to put her on a schedule. My 10 month old has been sleeping by himself since he was 4 weeks. My mom told me then to to start a routine of "going to bed" activities. It was the BEST advice I ever got. Now, he goes to bed in his room every night between 8 and 8:30. He hardly crys anymore. He knows when he gets a bath and bottle, bedtime is next. Its great for ALL parties. He gets the rest he needs and I get a little down time which is much needed with a full time job and baby.
