night time sleeper

i am having a increasingly hard time to get Adler down to sleep at reasonable hour (9p/10p.) the trade off is that she is sleeping 4-5 hours in a row waking up feeding and going back to sleep. anywhere from 5a/6a she wakes for another feeding and that time of day she does not go directly back to sleep no matter how much mommy pleads with her, so mommy can get an extra hour or two.
