Sarah, I understand the joys (not) of a baby who won't sleep well and everyone must do what they feel is best, but if you haven't done much research on the controlled crying, I urge you to read up on it for Bayleigh's sake. There are threads on the this site that discuss it and a lot of new research which shows it may not be the best course of action for babies' developing brains. Up to you of course but it never hurts to be informed IMO.
